How much fennel seed equals one fennel bulb?

Well, hello there! Fennel seeds and fennel bulbs have different flavors and textures, so they can't be used interchangeably. Fennel seeds have a more concentrated flavor compared to the bulb, so you'll need to use about 1 tablespoon of fennel seeds to replace one small fennel bulb in a recipe. Remember, cooking is all about experimenting and finding what works best for you! Happy cooking, my friend.
