🧂 Condiments & Sauces Storage Guide

Condiments are shelf-stable powerhouses thanks to high acidity, salt content, or sugar that naturally preserve them. However, storage needs vary significantly once opened. Here’s what you need to know about storing your most-used condiments.

Mustard Storage

One of the most misunderstood condiments. Should mustard be refrigerated? The answer is nuanced—it’s optional. Yellow mustard’s high acidity and vinegar content make it shelf-stable even after opening, though refrigeration extends its peak flavor quality. Learn more about whether mustard goes bad and how to spot signs of spoilage.

Ketchup & Tomato-Based Sauces

The ketchup refrigeration debate is real. Does ketchup go bad? Yes, but slowly. Unopened ketchup lasts a year in the pantry. Once opened, refrigeration is optional but recommended—it prevents the natural breakdown of tomato compounds and maintains that bright red color. Store opened ketchup in the fridge for optimal quality. If you’ve ever splashed some on your shirt, see our guide on how to get ketchup out of clothes.

Mayonnaise

This is non-negotiable: mayonnaise needs refrigeration after opening. Egg-based products are highly perishable. Unopened mayo can sit in the pantry for 3–4 months, but once you break that seal, it goes straight to the fridge. Wondering does mayo go bad? Yes—toss it after 2 months refrigerated or if you see any separation, discoloration, or off smell.

BBQ Sauce

BBQ sauce should be refrigerated after opening to maintain quality, though its high sugar and vinegar content provide some shelf stability. Unopened bottles last a year in the pantry. Once opened, refrigerate for 4–6 months of peak flavor. Check our guide on whether BBQ sauce goes bad to identify spoilage signs. If grilling season gets messy, we also have a guide on how to get BBQ sauce out of clothes.

Ranch Dressing

Ranch is one of the more perishable condiments due to its dairy and egg base. Ranch dressing must be refrigerated after opening. Unopened bottles are shelf-stable for 12–18 months in the pantry, but once opened, refrigerate and use within 1–3 months. Ranch dressing does go bad—watch for a sour smell, separation that won’t remix, or any visible mold.

Sriracha

Does sriracha need to be refrigerated? Technically no—its chili pepper base and high acidity keep it shelf-stable. Unopened bottles last up to 2 years in the pantry. Once opened, it can sit on the counter for up to 9 months, though refrigeration extends the bright flavor and color considerably longer. Sriracha does go bad—watch for darkening color, separation, or off odors.

Hot Sauce

Hot sauce is one of the most shelf-stable condiments you own, but storage needs vary significantly by sauce type. Vinegar-based red hot sauces like Frank’s RedHot are safe at room temperature after opening for months—their high acid content prevents bacterial growth. Green and tomatillo-based sauces degrade faster due to chlorophyll breakdown and lower capsaicin levels, so refrigerate after opening. Fermented hot sauces benefit from refrigeration to slow continued fermentation. Fruit-based and creamy hot sauces must always be refrigerated. Does hot sauce go bad? Yes—watch for mold, separation that won’t mix back, or an off smell. See also: does hot sauce need to be refrigerated? Splashed some on your shirt? See how to get hot sauce out of clothes.

Teriyaki Sauce

Teriyaki sauce gets its shelf stability from its soy sauce base, added sugar, and acidic ingredients like mirin or vinegar. Unopened bottles last 1–3 years in the pantry. Teriyaki sauce should be refrigerated after opening for best quality—major brands including Kikkoman recommend it. Opened and refrigerated, it stays at peak quality for up to a year. Learn more about whether teriyaki sauce goes bad and how to spot spoilage.

Asian Sauces: Soy, Worcestershire, Fish, Oyster & Hoisin

Fermented sauces vary widely in their refrigeration needs. Soy sauce doesn’t need refrigeration even after opening—its high salt content prevents bacterial growth. Same goes for Worcestershire sauce. However, fish sauce should be refrigerated after opening for best quality, and oyster sauce must be refrigerated after opening—it contains oyster extracts that deteriorate quickly at room temperature. Similarly, hoisin sauce needs refrigeration after opening to prevent fermentation and flavor loss. Wondering if these have gone off? See our guides on fish sauce, oyster sauce, and hoisin sauce spoilage.

Tahini

Tahini—ground sesame seed paste—has a higher oil content than most condiments, making it prone to rancidity. Tahini should be refrigerated after opening to preserve its nutty flavor and prevent the oils from going rancid. Unopened tahini lasts about a year at room temperature. Once opened, store in the fridge for up to 6 months. Tahini does go bad—a bitter, paint-like smell is the telltale sign.

Miso Paste

Miso is a fermented soybean paste with a long shelf life, but it still needs care. Miso paste must be refrigerated after opening. Properly refrigerated, it can last 3 months to over a year depending on salt content—white miso (lower salt) is more perishable than red or dark miso. Always press plastic wrap directly onto the surface to minimize oxidation. Miso paste can go bad; signs include a sour smell beyond its normal tang, or visible mold.

Anchovy Paste

A little goes a long way, which makes proper storage critical. Anchovy paste needs refrigeration after opening—it’s a fish-based product and is highly perishable once the tube or jar is unsealed. Use it within 1–2 months for best quality and flavor. Anchovy paste does go bad; discard it if you notice an overly pungent or off-putting smell beyond its normal briny aroma.

Capers

Capers are packed in either brine or salt, which provides significant natural preservation. Capers need refrigeration after opening. Always keep them submerged in their brine, which extends shelf life up to a year in the fridge. Without brine, they dry out and deteriorate within days. Capers can go bad—discard them if the brine becomes cloudy, slimy, or develops an off odor.

Jelly & Jam

High-sugar preserves are naturally shelf-stable, but jelly needs refrigeration once opened to prevent mold growth. Unopened jelly lasts 1–2 years in the pantry. After opening, refrigerate and use within 6–12 months. Learn the difference between spoilage and natural sugar crystallization in our guide on whether jelly goes bad. Looking for creative ways to use up the rest of the jar? Check out our ideas for using up extra jelly.

Relish

Relish is vinegar-based, which gives it strong natural preservation. Relish needs refrigeration after opening to maintain quality and prevent mold. Unopened jars last 1–2 years in the pantry; once opened, refrigerate and use within 9–12 months. There is no meaningful difference between sweet and dill relish on food safety—both follow the same rules. Relish does go bad—a bulging lid before opening, or an off smell and mold once opened, are the signs to watch for.

Salsa

Salsa shelf life depends almost entirely on which type you have. Jarred shelf-stable salsa lasts 1–2 years unopened and 1–4 weeks once opened and refrigerated. Store-bought refrigerated salsa (sold in the cold section) lasts 5–7 days opened. Fresh homemade or pico de gallo lasts 4–7 days. Cooked or roasted homemade salsa lasts 7–10 days. Does salsa need to be refrigerated? Once opened or homemade, always yes. Salsa does go bad—mold, off smell, excessive fermentation, or a watery separation that won’t stir back are the main signs.

Tartar Sauce

Tartar sauce belongs in a different safety category from most condiments because its base is mayonnaise, not vinegar. Treat it like mayo, not like ketchup or hot sauce. Unopened commercial tartar sauce is pantry-stable for 12–18 months. Once opened, it must be refrigerated and used within 6 months. Homemade tartar sauce made with commercial mayo lasts just 3–5 days refrigerated. Never leave tartar sauce at room temperature for more than 2 hours—the egg base creates genuine food safety risk, not just quality concerns. Does tartar sauce go bad? Yes, and faster than most people expect. See also: does tartar sauce need to be refrigerated?

Cocktail Sauce

Cocktail sauce occupies an interesting middle ground—its tomato and horseradish base give it reasonable acidity, but it’s more perishable than ketchup. Cocktail sauce should be refrigerated after opening. Unopened bottles last about a year in the pantry. Once opened, refrigerate and use within 3–6 months for best quality. The horseradish component is the weak link—it loses pungency and heat over time even when properly refrigerated. Cocktail sauce does go bad—watch for mold, an off smell, or a loss of the characteristic horseradish kick paired with darkening color.

Steak Sauce

Steak sauce—think A.1. or Worcestershire-style blends—gets its shelf stability from vinegar, salt, and sugar. Steak sauce should be refrigerated after opening for best quality, though its high acidity means it won’t become unsafe quickly at room temperature. Unopened bottles last 2–3 years in the pantry. Once opened, refrigerate and use within 6–12 months. Steak sauce does go bad—a significant change in color, visible mold, or an off fermented smell are the main signs to watch for.

Cooking Wine

Cooking wine storage rules depend entirely on the type. Shelf-stable cooking wines sold in non-refrigerated sections contain added salt and preservatives that extend their life significantly. Cooking wine should be refrigerated after opening regardless of type. Shelf-stable cooking wine lasts 1–2 months in the pantry but 3–6 months refrigerated. Regular drinking wine used for cooking should be refrigerated and used within 3–5 days. Cooking wine does go bad—a vinegary smell beyond the wine’s normal character, visible sediment, or a flat, off flavor are the signs it’s time to discard it.

Mustard Storage Note

🫒 Oils & Fats Storage Guide

Cooking oils and fats have unique storage needs based on their composition. Understanding proper storage prevents rancidity and preserves flavor and nutritional benefits. According to the National Center for Biotechnology Information, exposure to light, heat, and oxygen accelerates oil degradation.

Olive Oil

Olive oil does not need refrigeration—in fact, cold temperatures cause it to solidify and become cloudy. Store extra virgin olive oil in a cool, dark pantry away from the stove. Heat and light are olive oil’s enemies. Unopened bottles last 18–24 months. Once opened, use within 6–12 months for optimal flavor. Curious about whether olive oil goes bad? Yes—rancid oil smells like crayons or old nuts.

Coconut Oil

Coconut oil is one of the most shelf-stable cooking oils you can buy, thanks to its high saturated fat content. Coconut oil does not need refrigeration—store it in a cool, dark pantry. Virgin coconut oil lasts 2–3 years; refined coconut oil lasts 12–18 months. Solidifying at cooler temperatures is completely normal and not a sign of spoilage. Coconut oil does go bad—rancid oil smells sour, stale, or musty. For culinary ideas and benefits, explore our guide on coconut oil uses.

Avocado Oil

Avocado oil has a shorter shelf life than most people expect given its premium price. Avocado oil does not need refrigeration—cold temperatures cause it to solidify and turn cloudy, which is harmless but inconvenient. Store it in a cool, dark pantry away from heat and light. Unopened avocado oil lasts 12–24 months depending on the brand and processing method; once opened, use within 3–6 months. A 2020 UC Davis study found that 82% of avocado oil samples tested were either rancid or adulterated before their expiration dates, making brand quality and proper storage especially important. Avocado oil does go bad—rancid oil smells waxy, like old crayons or paint.

Sesame Oil

Sesame oil is more prone to rancidity than olive or coconut oil because its polyunsaturated fats oxidize faster. Sesame oil should be refrigerated after opening to significantly extend its shelf life—unopened it lasts up to 2 years in the pantry, but once opened it lasts only about 6 months at room temperature versus up to a year refrigerated. Toasted sesame oil, used as a finishing oil in Asian cooking, is especially prone to going rancid and benefits most from refrigeration. Sesame oil does go bad—a sharp, paint-like, or stale smell is the clear sign it has turned.

🍫 Dessert Sauces & Sweet Toppings Storage Guide

Sweet toppings like chocolate syrup, caramel sauce, and frosting seem like they’d last forever thanks to their high sugar content—but once opened, they’re more perishable than most people realize.

Chocolate Syrup

That bottle of chocolate syrup in your fridge door is more time-sensitive than it looks. Chocolate syrup must be refrigerated after opening—its cocoa content, milk solids, and moisture make it susceptible to mold even at room temperature. Unopened, it lasts 2–3 years in the pantry. Once opened, refrigerate and use within 1–2 months. Chocolate syrup does go bad—signs include mold, an off or fermented smell, or any significant change in texture or color.

Caramel Sauce

Caramel sauce storage rules depend on what’s in it. Commercial caramel sauces with preservatives have some pantry stability when unopened (1–2 years) but should always be refrigerated after opening. Once open, pantry storage is fine for 2–4 weeks for high-sugar commercial varieties, but refrigeration extends it to 2–3 months. Dairy-based caramel (like dulce de leche or homemade) must always be refrigerated and used within 2–3 weeks. Caramel sauce does go bad—watch for mold, an off smell, or crystallization that doesn’t dissolve when warmed.

Frosting

Store-bought canned frosting surprises a lot of people. Frosting should be refrigerated after opening—its fat content makes it susceptible to spoilage at room temperature over time. Unopened cans are shelf-stable for 12–18 months. Once opened, refrigerate and use within 3–4 weeks. Homemade buttercream made with real butter can sit at room temperature for 1–2 days but should be refrigerated for longer storage. Cream cheese frostings and whipped cream frostings must always be refrigerated and used within a week. Frosting does go bad—discard if you see mold, notice a sour smell, or the texture has changed dramatically.

🧈 Dairy & Fresh Refrigerated Foods Storage Guide

Dairy products and fresh refrigerated foods require consistent cold storage—these are among the highest-risk categories for foodborne illness if stored improperly. Unlike condiments and oils, most dairy items have little room for error.

Butter

Butter is one of the more forgiving dairy products thanks to its very high fat content (80%) and low moisture, but it does go bad. The key distinction is salted versus unsalted. Does butter need to be refrigerated? Salted butter can sit on the counter in a covered dish for 1–2 days per USDA FoodKeeper guidance; unsalted always belongs in the fridge. Refrigerated, salted butter lasts 1–3 months; unsalted up to 1 month. Both freeze well for up to 12 months. Whipped and flavored butters must always be refrigerated and used within 1–2 weeks. Clarified butter and ghee are a completely different category—shelf-stable at room temperature for 3–6 months in an airtight container. Does butter go bad? Yes—rancid butter smells sour, soapy, or like old paint. That is oxidation, not bacterial spoilage, and it will ruin anything you cook or bake with it.

Sour Cream

Sour cream is one of the more perishable dairy staples in your fridge. Sour cream must always be refrigerated—it should never sit at room temperature for more than 2 hours. Unopened, it lasts 2–3 weeks past its sell-by date when properly refrigerated. Once opened, use within 7–10 days for best quality. Always use a clean spoon to avoid introducing bacteria from other foods. Sour cream does go bad—discard it if you see mold, notice excessive liquid separation that doesn’t stir back, or detect a sour smell that goes beyond its natural tang.

Cream Cheese

Cream cheese has a shorter window than most people realize. Cream cheese must always be refrigerated and should never be left at room temperature for more than 2 hours. Unopened blocks or tubs last 3–4 weeks past the sell-by date in the fridge. Once opened, use within 10–14 days. Foil-wrapped cream cheese stays fresh longer than tub varieties once opened. Cream cheese does go bad—watch for mold of any color, a sour or off smell, or a dry, crumbly texture where it was previously smooth.

Cottage Cheese

Cottage cheese is highly perishable and one of the shortest-lived dairy products in your fridge. Cottage cheese must always be refrigerated—its high moisture content makes it an ideal environment for bacterial growth at room temperature. Unopened, it typically lasts 1–2 weeks past the sell-by date. Once opened, use within 5–7 days and always keep it tightly sealed. Store it toward the back of the refrigerator where temperatures are most consistent. Cottage cheese does go bad—discard it if you see any mold, notice a sour or off smell beyond its mild tang, or find the texture has become overly watery or slimy.

Nacho Cheese Sauce

Canned or jarred nacho cheese sauce is shelf-stable when sealed, but its dairy content makes it highly perishable once opened. Nacho cheese sauce must be refrigerated after opening and should be used within 3–5 days. Unopened cans last 12–18 months at room temperature. Never leave nacho cheese out longer than 2 hours during serving—this is a genuine food safety concern, not just a quality issue. Nacho cheese sauce does go bad—look for mold, a sour or off smell, or any separation that doesn’t remix when stirred.

🥚 Eggs Storage Guide

Eggs are among the most important foods to store correctly, and the rules differ dramatically depending on where in the world you are.

Eggs

Do eggs need to be refrigerated? In the United States, the answer is a firm yes. American commercial eggs are washed during processing, which removes the natural protective coating (called the “bloom” or cuticle) that seals the shell’s pores and protects the egg from bacteria. Without this coating, eggs are vulnerable to contamination and must be refrigerated immediately after purchase. US eggs stored in the fridge stay fresh for 3–5 weeks past the pack date. In Europe and many other countries, eggs are not washed and therefore retain their bloom, making refrigeration unnecessary—they can sit on the counter for up to 2 weeks safely.

Never wash your eggs before storing them—this removes any remaining protective coating and accelerates spoilage. Store eggs in their original carton, toward the back of the refrigerator where temperature is most stable (not the door, which fluctuates). Do eggs go bad? Yes—use the float test: place the egg in a bowl of cold water. Fresh eggs sink and lie flat; older but still safe eggs tilt upward or stand upright; eggs that float should always be discarded. A sulfur or rotten smell when cracking is the definitive spoilage sign regardless of the float test result.

🍯 Sweeteners Storage Guide

Natural sweeteners have impressive shelf lives thanks to their low water activity and high sugar content, which inhibit microbial growth. However, storage methods vary by type.

Honey

Here’s a fascinating fact: honey never needs refrigeration, and honey never goes bad. Archaeologists have found 3,000-year-old honey in Egyptian tombs that’s still edible. Store honey at room temperature in a sealed container. If it crystallizes, that’s natural—gently warm the jar in hot water to return it to liquid form. Refrigeration actually speeds crystallization and makes honey harder to use.

Maple Syrup

Pure maple syrup tells a different story. Unopened, it lasts indefinitely in the pantry. However, maple syrup needs refrigeration after opening because it contains enough moisture to support mold growth. Refrigerated opened syrup lasts about a year. Check our detailed guide on whether maple syrup goes bad to identify mold vs. crystallization.

Molasses

Molasses doesn’t require refrigeration thanks to its high sugar concentration. Store it in a cool pantry, tightly sealed. Unopened molasses lasts 1–2 years; opened lasts 6 months to a year. Learn more about whether molasses goes bad and how to spot fermentation.

🥒 Fermented & Pickled Foods Storage

Fermented foods are preserved through beneficial bacteria, but they still have specific storage needs once exposed to air. The fermentation process creates an acidic environment that inhibits harmful bacteria, but oxidation and temperature affect quality.

Sauerkraut

Store-bought sauerkraut is typically pasteurized, meaning beneficial bacteria are killed for shelf stability. Sauerkraut needs refrigeration after opening to prevent spoilage and maintain texture. Unopened jars last 1–2 years in the pantry. Once opened, refrigerate and use within 4–6 months. Want to make your own? Try our easy homemade sauerkraut recipe and learn about sauerkraut’s health benefits. Wondering does sauerkraut go bad? Yes—look for off smells, sliminess, or mold.

🥫 Pantry Staples Storage Guide

Coconut Milk

Canned coconut milk is shelf-stable for 2–5 years unopened. Once opened, the rules change dramatically. Coconut milk must be refrigerated after opening and used within 4–7 days. Transfer it to an airtight container—never store it in the open can. Coconut milk does go bad; signs include a sour smell, curdled texture, or any visible mold. Carton coconut milk follows the same rules: refrigerate after opening and use within 7–10 days.

Sun-Dried Tomatoes

Sun-dried tomatoes come in two forms—dry-packed and oil-packed—and they have very different storage needs once opened. Sun-dried tomatoes need refrigeration after opening regardless of type. Dry-packed last 1–2 weeks refrigerated; oil-packed last 1–2 months as long as the tomatoes stay submerged in oil. Unopened, either type lasts 1–2 years in the pantry. Sun-dried tomatoes do go bad—discard if the oil smells rancid, you see mold, or the texture becomes unusually slimy.

Oatmeal

Dry oatmeal is one of the most shelf-stable pantry staples you own, but it still has limits. Oatmeal doesn’t need refrigeration in its dry, uncooked form—store it in an airtight container in a cool, dry pantry. Unopened rolled oats or steel-cut oats last 1–2 years at room temperature. Once opened and stored properly, they last about the same time. Instant oatmeal packets with flavorings and mix-ins have a shorter shelf life of about 1 year due to added dairy and sugar ingredients. Cooked oatmeal is a completely different story—it must be refrigerated within 2 hours and used within 4–5 days. Oatmeal does go bad—a rancid or stale smell, presence of pests, or visible mold are the signs to watch for in dry oats. In cooked oatmeal, look for mold or any off smell.

Cornmeal

Like oatmeal, dry cornmeal is shelf-stable but not invincible. Cornmeal doesn’t need refrigeration when stored dry and sealed, but refrigeration or freezing significantly extends its life—particularly for stone-ground or whole-grain varieties which retain the germ and are higher in oils. Standard degerminated cornmeal lasts 1–2 years in the pantry in an airtight container. Stone-ground cornmeal lasts only 3–6 months at room temperature due to its higher oil content—refrigerate or freeze it for up to 1–2 years. Cornmeal does go bad—rancidity (a sour, musty, or paint-like smell) is the main spoilage sign, along with any evidence of pests or moisture clumping.

🌶️ Specialty Items Storage Guide

Peanut Butter

Commercial peanut butter with stabilizers doesn’t need refrigeration—the added oils and preservatives keep it stable at room temperature. However, peanut butter does go bad over time. Unopened jars last 6–9 months in the pantry. Once opened, use within 2–3 months for best quality. Natural peanut butter (just peanuts and salt) should be refrigerated after opening to prevent oil separation and rancidity.

Horseradish

Fresh horseradish’s pungent compounds start breaking down immediately after the root is cut. Prepared horseradish needs refrigeration to slow this process. Horseradish does go bad—it loses potency and develops off flavors. Refrigerate opened jars and use within 3–4 months for maximum heat and flavor.

Apple Cider Vinegar

Apple cider vinegar does not need refrigeration. Its high acidity (pH around 3) creates an inhospitable environment for bacteria. Store it in a cool pantry, and it lasts indefinitely. That cloudy “mother” you see in raw ACV is beneficial bacteria—it’s normal and safe. Beyond cooking, explore apple cider vinegar tonics for wellness benefits.

Vanilla Extract

Vanilla extract doesn’t need refrigeration. Pure vanilla extract is alcohol-based (typically 35–40% alcohol), which preserves it indefinitely. Store it in a cool, dark place tightly sealed. The flavor actually improves with age. Imitation vanilla extract is also shelf-stable but won’t improve over time.

Arugula

Storing arugula properly is key to extending its short shelf life. Always refrigerate arugula—it wilts quickly at room temperature. Store unwashed arugula loosely wrapped in a dry paper towel inside an airtight bag or container, in the crisper drawer. It stays fresh for 3–5 days. Washing before storage accelerates wilting, so wait until just before use.

Why Refrigeration Matters

Refrigeration slows bacterial growth and chemical reactions that cause food spoilage. According to the CDC, keeping perishable foods below 40°F (4°C) significantly reduces the risk of foodborne illness.

What happens at room temperature?

Between 40°F and 140°F (4°C to 60°C) is the “danger zone” where bacteria multiply rapidly. Foods left in this range for more than 2 hours (or 1 hour above 90°F) should be discarded according to FoodSafety.gov guidelines.

The role of preservatives:

Salt, sugar, acid, and alcohol are natural preservatives that inhibit microbial growth. Foods high in these compounds (like mustard, soy sauce, honey, and vanilla extract) are more shelf-stable than low-acid, low-sugar foods (like mayonnaise and fresh dairy).

5 Rules for Proper Food Storage

1. Check Expiration Dates & Product Dating

Understand the difference: “Best By” indicates peak quality (not safety). “Use By” is the last date for peak quality. “Sell By” tells retailers when to rotate stock. Learn more from the USDA’s Food Product Dating guide.

2. Store Foods in Proper Containers

Transfer opened items to airtight containers to prevent oxidation, moisture loss, and cross-contamination. Glass and BPA-free plastic containers work best. Always label containers with contents and opening date.

3. Maintain Refrigerator Temperature

Keep your refrigerator at 40°F (4°C) or below and your freezer at 0°F (-18°C). Use a refrigerator thermometer to verify—built-in displays aren’t always accurate.

4. Practice FIFO (First In, First Out)

Rotate stock by placing new items behind older ones. Use older products first to minimize waste. This is standard practice in professional kitchens and should be in home kitchens too.

5. Trust Your Senses

Dates are guidelines, not absolutes. If food looks, smells, or tastes off, throw it out—even if it’s within the date range. Conversely, properly stored foods often remain safe past their “best by” date.

When to Throw Food Away

Visual signs:

• Mold growth (fuzzy spots, discoloration)
• Separation or texture changes
• Discoloration (browning, darkening)
• Bulging containers or lids

Smell indicators:

• Sour or fermented odor (when it shouldn’t be fermented)
• Rancid or “off” smell
• Any unnatural or chemical odor

Texture changes:

• Sliminess or stickiness
• Excessive thickness or thinning
• Gas bubbles or fizzing (in non-carbonated items)

Safety rule: When in doubt, throw it out. The cost of replacing food is far less than the risk of foodborne illness. For a detailed breakdown of which expired condiments pose the most risk, see: These Expired Condiments Could Actually Make You Sick.
