– 2-3 cloves garlic
Roast 3-4 tomatoes or enough to fill about 2/3 of a blender. To roast, put on a dry griddle on a high fire until partially blackened or blistered. You will want to rotate them every little bit. Also, roast 2 serrano peppers & 2-3 cloves of garlic. Put all of this in a blender with about 1/2 of a small to medium white onion, and about 1/4 cup of cilantro. Blend well.
