Expiration & Storage Tips
When does unsweetened cocoa powder expire?
Unopened cocoa powder can last for two to three years if stored properly. Once opened, it's best to consume it within one year, although many homemade bakers have found that the flavor can last far longer. If you've frozen your cocoa powder, just remember to use it up quickly after you've defrosted it to ensure you're using it at its best.
How do you tell if unsweetened cocoa powder is bad?
Smell and visual appearance are going to be your best friends here. If your unsweetened cocoa powder smells off, or if you can see any mold or bugs, then it's best to toss it. Cocoa powder is naturally a deep, dark brown - any color changes can signal that it's time to replace your stash. Lastly, if it's unusually clumpy or compacted, it's a sign of moisture contamination, which could mean it's gone bad.
Tips for storing unsweetened cocoa powder to extend shelf life
• Store your unsweetened cocoa powder in an airtight container, and out of direct sunlight.
• The pantry is perfect - it's cool, dry and dark.
• Avoid storing this sensitive ingredient near spices or odorous foods as it can absorb their aroma.
• If you want to freeze your cocoa powder, ensure it's in a well-sealed container. This can extend its life for several years, although the flavor may be slightly different after defrosting.
• To defrost, just remove the powder from the freezer and let it reach room temperature before using. Do not add any heat as this can ruin the flavor.
