If you have whole spices like anise stars, coriander seeds, cumin seeds, dill or plenty of others, you can try planting them to see if they grow. Since these types of spices were seeds all along, they may germinate, though success may depend on how old those seeds are. (If you’ve had those caraway or mustard seeds in the back of the pantry for the last decade, you may be out of luck.)
With any spice, it’s important to store it properly to maintain freshness as long as possible. Storing spices in airtight, glass containers is ideal, and keeping them in the refrigerator can make them last longer as well. Whatever you do, don’t store them above the stove, explains The Spice House, because the heat will destroy the spices’ oils.
