Epazote
Epazote is the essential herb of Mexican and Central American cooking — an aromatic annual with pungent, complex leaves that are traditionally used to season black beans, soups, tamales, and quesadillas with a distinctive flavor that's earthy, herbal, and impossible to substitute. Beyond its culinary role, epazote is well-known for its digestive properties, traditionally added to bean dishes to reduce their notorious side effects. Vigorous, self-seeding, and easy to grow in any sunny spot.
