How to Pressure-Cook Tomatillos

Tomatillos are small, green fruit with a papery husk. Contrary to what their name indicates, tomatillos are not related to tomatoes. Instead, they are part of the gooseberry family. These fruit are often used in Mexican cooking. Tomatillos have a tart flavor that combines well with chiles, cheese and sour cream, as well as other spicy flavors.
