What Are Fennel Seeds?
Fennel seeds come from the fennel plant (*Foeniculum vulgare*), which belongs to the carrot family (Apiaceae). Despite being called “seeds,” they’re technically dry fruits — kind of like how sunflower seeds aren’t really seeds either. They grow in clusters and are harvested when mature and dried.

Taste Profile: Sweet Like Licorice, But Make It Spicy
If you’ve ever tasted black licorice, you know where fennel’s flavor comes from — anethole, the same aromatic compound found in star anise and licorice root. However, unlike its sweeter cousin, fennel seed offers a balanced earthiness with a slight bitterness that makes it versatile in both sweet and savory dishes.
Flavor Note | Description |
---|---|
Sweetness | Mildly sweet, reminiscent of anise/licorice |
Earthy | Rooty, herbal undertones |
Heat Level | None – it's not spicy hot, just warming |
