unopened pantry (dry mix)6-12 months past 'Best By' date
Signs of Spoilage
Significant hardening or clumping that cannot be broken apart, visible mold (extremely rare if sealed), discoloration, strong off-odor.
How to Check
Check the 'Best By' or 'Use By' date. Visually inspect for any signs of moisture intrusion, discoloration, or foreign growth. Give it a sniff for any unusual or chemical odors. If it's just past the date and looks/smells fine, it's likely still safe, though flavor might be diminished.
Storage Tips
Store in a cool, dark, dry place away from direct sunlight and heat sources. Ensure the packaging remains intact and sealed.
prepared au jus (fridge)3-4 days
Signs of Spoilage
Sour, yeasty, or unpleasant smell; cloudy or murky appearance; visible mold growth on the surface; sliminess or thickening; off-flavor.
How to Check
The smell test is crucial: any sour or off-odor is a strong indicator of spoilage. Visual inspection: Look for cloudiness, separation, or any fuzzy mold. Texture: If it appears slimy or unusually thick, discard. Do not taste if any of these signs are present.
Storage Tips
Cool down prepared au jus quickly before refrigerating (within 2 hours of cooking). Store in an airtight container to prevent absorption of other food odors and to protect it from contaminants. Reheat thoroughly to 165°F (74°C) before serving.
prepared au jus (freezer)2-3 months for best quality (safe indefinitely at 0°F / -18°C)
Signs of Spoilage
Freezer burn (dry, discolored patches), significant change in texture (e.g., graininess) upon thawing, noticeable loss of flavor. These are quality issues, not safety issues if properly frozen.
How to Check
Visually inspect for signs of freezer burn. Upon thawing, check the smell and appearance as you would for refrigerated au jus. If it smells off or has mold 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. Thaw overnight in the refrigerator before reheating. Do not refreeze thawed au jus.
opened pantry (dry mix)6-12 months (or until 'Best By' date, whichever comes first)
Signs of Spoilage
Hardening, clumping, loss of potency/aroma, stale or chemical odor, discoloration, presence of pantry pests if not sealed properly.
How to Check
Visually inspect for excessive clumping or hardening that doesn't easily crumble. Sniff for a stale, musty, or 'off' smell. The flavor will be noticeably weaker or 'flat' if it's past its prime. If there are any signs of mold or pests, discard immediately.
Storage Tips
Transfer to an airtight container (like a jar or a sealed plastic container) to protect from moisture, air, and pantry pests. This will help maintain its flavor and prevent clumping.
