Fennel seeds can be used whole or ground and are used in both savory and sweet dishes. They are commonly found in sausages, breads, curries, salads, pickles, and desserts.Fennel seeds are rich in nutrients such as fiber, vitamins (especially vitamin C), and minerals (such as potassium, magnesium, and calcium).
