Fennel seeds are available year around in the markets either in the form of seeds or processed ground form. In the store, buy whole fennel seeds instead of powder since oftentimes it may contain adulterated spicy powders. Store dry fennel seeds as you do in case of other seeds like caraway, dill, etc. Place whole seeds in a clean air-seal container and store in cool, humid free and dark place. Ground and powdered fennel should be stored in the refrigerator in airtight containers and should be used sooner since it loses flavor quickly due to evaporation of its essential oils.
