Welcome to some very simple green sauce with a Mexican flair. About a decade ago, a friend of mine taught me to make a sauce with these basic ingredients.  I have been perfecting this recipe since then.  I will pass along the exact measurements as I figure them out, but here is the quick overview.

First get a couple pounds of tomatillos then peel and wash them. Next chop 4-5 garlic cloves into thin slices.  Add 4-5 de-seeded jalapeño peppers.  Add 2-3 pinches of cumin seed.  Put all this ingredients into a frying pan and turn on the heat to medium.  Add salt.  Stir a couple of times until the tomatillos change from bright to more of an olive green.  Dump the contents of the pan into a blender along with some fresh cilantro (1- 2 tablespoons compressed leaves/stems).  Add some water to the pan to de-glaze and dump it into the blender along with about 1/3 to 1/3 cup of white vinegar. Blend, blend, blend.  Taste.  Add salt and/or more vinegar to taste. Blend some more.  Dump into a glass jar and let it cool.  Refrigerate when cool.  Should keep for many weeks in the fridge,
