Can You Cook With Expired Spices?

The spice rack is one of the most essential and eclectic elements of any kitchen, with a wide variety of flavors that add depth to any dish. Chances are you own more spices than you know what to do with, which results in half-full jars sitting there long past their “best by” date. However, unlike other foods, these expiration dates aren’t so hard and fast. You might be able to use expired spices much longer than you think. 

What to Know About “Expired” Spices

Spices lose their potency over time. However, spices don’t expire in the way that milk or meat goes bad because dried spices are inhospitable to bacterial and fungal growth. Depending on how a spice is processed, it can remain flavorful and potent between one and four years. Dried herbs such as basil, oregano, rosemary, and bay leaves retain their flavor for one to three years. Ground spices like powdered ginger, garlic powder, and ground cinnamon remain potent for two to three years. Whole spices, such as peppercorns, caraway seeds, and cinnamon sticks, can last up to four years.

How to Store Spices

To keep them potent for as long as possible, store spices in a place with limited exposure to heat, air, and moisture, such as a tightly sealed jar inside a cool, dark cabinet. Avoid storing spices in clear jars on countertops. While this may be more convenient when preparing meals, exposure to light and heat can cause the spices to lose flavor faster.

To test if a spice is still potent, take a small amount and rub it between your fingers to generate an aroma. Note how strong the smell is — is it sharp or lackluster? Next, put a pinch of the spice on your tongue to test the flavor. If the smell or taste is lacking, the spice is probably past its prime and should be replaced.

Alternative Uses for Old Spices

Don’t throw out old spices — there are plenty of other ways to use them outside of the kitchen. Some spices repel pests. For example, cinnamon deters ants, while bay leaves repel cockroaches. 

You can also use colorful spices, like turmeric or paprika, to create natural dyes. Wrap 1 to 2 tablespoons of the spice in cheesecloth and boil it in 2 cups of water for one hour before adding 1 cup of vinegar and the fabric you want to dye. Let the ingredients simmer for 30 minutes before removing the fabric to dry.
