I have started to make a Tomatillo salsa that is very simple and all natural... not to mention very good. It only has 6 ingredients... tomatillos (1lb),onion (1),garlic (1 whole head), jalapenos (2-4 unseeded) ,cilantro (1/3-1/2 bunch),salt.
De-husk and wash the tomatillos, skin and quarter onion, remove the skins from the garlic and separate into whole cloves, cut stem off jalapenos. Add everything to foil pan and coat with a litte oil/vingear/lime juice/salt.
Then put everything under a broiler and roast till charred. Remove from oven and rotate the tomatillos and jalpenos to make sure both sides are charred. I leave the onion and garlic alone.
Then add everything to a food processor and blend to desired consistency. Finally add the cilantro and pulse in blender till Cilantro is incorporated.
To add a bit of extra flavor you can roast the veggies over wood fire but not necessary.
