In gastronomy, fennel powder is commonly used in spice blends, such as garam masala in Indian cuisine or Chinese five-spice powder. It is a key ingredient in curries, marinades, and sauces, as it adds a warm and slightly sweet touch. It is also used in baking, especially in artisan breads and spiced cookies, where it provides a deeper flavor profile.

An interesting fact is that fennel powder has traditionally been used in some cultures to flavor liqueurs and beverages. In Italy, for example, it is a component of the famous sambuca, while in France, it can be found in certain varieties of absinthe. Additionally, its combination with citrus or spicy ingredients in sauces and stews enhances its anise-like profile, making it an excellent spice for balancing both sweet and savory flavors.
