I love to make this when using up a leftover bunch of cilantro from the fridge. Purchasing the few tomatillos and chiles costs only about $0.75, making this a cheap and delicious way to keep any of the fresh herb from going to waste.
5 medium tomatillos
1/4 cup water
2 serrano chiles
handful chopped cilantro
1/4 cup finely chopped onion
1/4 teaspoon salt
Peel and wash the tomatillos. Split and seed the chiles. Place the tomatillos and chiles under a broiler for about 4 minutes each side.
Transfer the blackened tomatillos, chiles, and any juices from the pan to a blender or food processor. Simply add the rest of the ingredients and blend.
This is the absolute basic recipe. For something more like my sister's version, try adding garlic, cumin, and/or lime. Or, you might have some other good additions in mind. If so, please share below!
