Tomatillos look like small green tomatoes (of which they are a distant relative) covered with a papery husk. They have a bright, lemon-like flavor perfect with spicy food or alongside grilled items. They can also add a nice hit of acid to stews and other heavy fare.
Tomatillos are small, round fruits harvested in late summer and into fall. They would ripen to yellow, red, or purple if we let them, but unripe – green – tomatillos, oddly, have more flavor.
How to Choose Tomatillos
Look for tomatillos that are firm but not rock-hard with their husks more or less intact (split open is fine, but you don't want them to have been handled so much that the husks are ripped off).
How to Store Tomatillos
Store tomatillos briefly at room temperature or for up to a week wrapped loosely in plastic in the fridge.
How to Use Tomatillos
The papery husks on tomatillos are pretty, but they need to be removed before cooking. Rinse de-husked tomatillos – they may well feel a bit sticky, that's okay.
Tomatillos are often used chopped and cooked into sauces to play a background note. Tomatillos fabulous lemon-y flavor can carry a dish, though, such as this Grilled Tomatillo Salsa or Green Chile Tomatillo Soup.
