unopened pantry1-2 years from purchase date, or 6-12 months past 'best by' date for optimal quality
Signs of Spoilage
Bulging or leaking can/jar, rust on the can, broken seal, mold growth (extremely rare in unopened), foul odor upon opening, significant discoloration or separation upon opening.
How to Check
Visually inspect the container for any damage (bulges, leaks, rust) before opening. Upon opening, listen for a 'pop' indicating the vacuum seal release. Immediately smell for any sour, metallic, or off-odors. Look for unusual colors or mold.
Storage Tips
Store in a cool, dark, and dry place away from direct sunlight and extreme temperature fluctuations. While it may be safe beyond the 'best by' date, quality (flavor, texture) may diminish over time.
opened fridge5-7 days
Signs of Spoilage
Visible mold growth (white, green, black fuzzy spots), sour, yeasty, or fermented smell, bubbling or fizzing, significant discoloration (darker, or unusual hues), an 'off' or unpleasant taste.
How to Check
Visually inspect the surface and sides for any mold growth or bubbling. Sniff the sauce for any sour, fermented, or 'off' odors. If no visual or smell signs, a tiny taste test can confirm freshness, but if there's any doubt, discard. Never taste if mold is present.
Storage Tips
Transfer any unused sauce to a clean, airtight container (glass or plastic) to prevent absorption of fridge odors and slow spoilage. Always use a clean spoon each time you retrieve sauce to avoid introducing bacteria. Do not leave opened sauce at room temperature for extended periods.
freezer4-6 months for best quality, safe indefinitely at 0°F (-18°C)
Signs of Spoilage
Significant freezer burn (dry, discolored patches), excessive ice crystals, loss of flavor and texture upon thawing (becoming watery or mushy). While safe, quality deteriorates.
How to Check
Before freezing, ensure the sauce smells and looks fresh. After thawing, check for excessive wateriness or a bland flavor. If it develops an off-odor after thawing, discard.
Storage Tips
Freeze in airtight, freezer-safe containers or heavy-duty freezer bags. Leave about an inch of headspace if using rigid containers, as liquids expand when frozen. Label with the date. Thaw in the refrigerator overnight or using a microwave's defrost setting. Do not refreeze thawed tomato sauce.
