unopened, cool, dark pantryFollow 'best by' date, up to 1-3 months past for quality
Signs of Spoilage
Rancid or stale odor, bitter or sour taste, dull or discolored appearance, visible mold (rare if properly sealed).
How to Check
Smell Test: Sniff for a paint-like, stale oil, or sour smell. Fresh nuts have a mild, sweet, nutty aroma. Visual Inspection: Check for any dark spots, fuzzy mold, or a generally dull, greasy appearance. Taste Test: If the smell and appearance are acceptable, taste a tiny piece. A bitter, metallic, or unpleasant flavor indicates rancidity.
Storage Tips
Store in a cool, dark place away from direct sunlight and heat, which accelerate rancidity. Keep in original airtight packaging until ready to use.

Signs of Spoilage
Strong rancid, stale, or sour odor; distinctly bitter, metallic, or sour taste; very dull or greasy appearance.
How to Check
Smell Test: This is the primary indicator. A strong off-odor is a clear sign. Taste Test: If the smell is questionable but not definitively bad, taste a very small amount. Discard immediately if it tastes bitter or unpleasant. Visual Inspection: Look for any signs of mold, discoloration, or a sticky/oily residue that wasn't present before.
Storage Tips
Transfer opened crushed nuts to an airtight container (like a glass jar or heavy-duty resealable bag) to minimize air exposure. This method is not recommended for long-term storage due to rapid quality degradation.
in refrigerator (opened or unopened)2-4 months
Signs of Spoilage
Rancid smell (less pronounced than at room temperature but still detectable), bitter or off-taste, slight darkening or dullness.
How to Check
Smell Test: Check for any sour, paint-like, or stale oil odors. Visual Inspection: Look for any signs of mold (more likely if moisture is present) or significant discoloration. Taste Test: If smell and appearance are fine, taste a small amount. Discard if it tastes bitter or unpleasant.
Storage Tips
Always store crushed nuts in an airtight container (glass jars, plastic containers with tight lids, or heavy-duty freezer bags) to prevent them from absorbing odors from other foods and to protect them from moisture. Bring to room temperature before using in recipes where texture is critical.
in freezer (opened or unopened)6-12 months (or longer for quality)
Signs of Spoilage
Very rare if properly stored. Possible slight freezer burn (dry, discolored spots) which affects texture but not safety. Extremely slow development of rancid smell/taste over very long periods.
How to Check
Smell Test: Should still smell fresh and nutty. An off-odor indicates very old or improperly stored nuts. Visual Inspection: Check for excessive freezer burn. Texture Test: Frozen nuts might be slightly softer or drier if freezer-burned, but should not be mushy.
Storage Tips
Store in heavy-duty freezer bags or airtight freezer-safe containers. Squeeze out as much air as possible to prevent freezer burn. Label with the date. Crushed nuts can often be used directly from the freezer in baking or as toppings without thawing.
