Ingredients

10 small purple or green tomatillos, about 10 ounces total, husked and washed 

1/2 small onion, coarsely chopped 

2 jalapeno chiles, coarsely chopped 

6 sprigs fresh cilantro, leaves only 

1 1/2 teaspoons coarse salt 

Preparation

Put tomatillos in a medium saucepan; cover with water by 1 inch. Bring to a boil. Reduce to a simmer. Cook 4 minutes. Drain, reserving 1/2 cup cooking liquid.

Process tomatillos, onion, jalapenos, cilantro, salt, and 1/4 cup liquid in a blender until a slightly chunky sauce forms, adding more liquid as needed.
