Tomatillo (Physalis philadelphica)

If you've tasted salsa verde, you've likely had a tomatillo. Known for its durability and versatility, this fruit is a staple in Mexican and Central American green sauces. Tomatillos are encased in a papery husk that must be peeled away before eating, as the rest of the plant is toxic. Besides being a key ingredient in sauces, tomatillos can replace tomatoes in recipes or be dried for snacking.
