Fennel seeds are small, oval-shaped seeds that come from the fennel plant, scientifically known as Foeniculum vulgare. They have a greenish-brown color and a distinctive sweet, licorice-like flavor with hints of anise. Fennel seeds are commonly used as a spice in cooking, particularly in Mediterranean, Indian, and Middle Eastern cuisines. They are often added to dishes to enhance flavor, such as in spice blends, marinades, and baked goods. In addition to their culinary uses, fennel seeds are known for their potential health benefits, including aiding digestion, reducing bloating, and acting as a natural breath freshener. They contain essential nutrients like fiber, antioxidants, and various vitamins and minerals. Fennel seeds can be used whole, ground, or as an extract, making them a versatile ingredient in both savory and sweet recipes.
