While licorice is a controversial flavor, fennel has many varied uses and should have a spot in home kitchens. It's used in spice rubs, as a breath freshener, and sometimes as a tea. It can be used in savory or sweet applications and benefits from being crushed a little before use. Fennel pairs well with pork and beef, so adding some to sausages and roasts will definitely improve the outcome.
