A mexican recipe of salsa verde. In Mexican cooking, a molcajete is a pre-Hispanic mortar and pestle made from volcanic stone. Molcajetes have two pieces: the basin and the tejolote, or grinder. Salsa verde is really easy to make from scratch, all you need are tomatillos, onion, jalapeño, lime, and cilantro. To make the salsa verde, you will need to cook the tomatillos, which you can do by either boiling them, broiling them in the oven, or pan roasting them.
