Here's what you need:
5 tomatillos per 1 yellow onion
Several Garlic Cloves (suit to how much you like garlic. I heart the stuff so I used a LOT-o)
Juice from 3 limes
1t each: salt, pepper, caynenne pepper, oregano (I happened to have Ground White Pepper on hand and it was delicious-i-o-so instead of black pepper, made it kind of smoky)
Peel your onion & tomatillos and rinse them. (PS- I think tomatillos are weird little things) With a small coring knife remove the core. Put in a pot with the onion and cover with water. Bring to a boil and let simmer about 10 minutes or until they are a light green. You don't want them to mushy or they fall apart. Drain, cut both ends of your onion and throw all of it in the blender or food processor, and set it to the side.
Notice the one on the top that refused to change color with the rest of them....if that tomatillo were a kid it would be a goth kid....just HAVING to be different! Why don't you just go hang out with the jalapenos. Geez...CONFORM damn you.
Roast your japapenos until they are charred BLACK. Like Goth Black. You can do this in the oven on broil or over a flame on a gas stove. Once they're done, place them in a sealed ziplock bag and let them steam for 10 minutes. Remove them from the bag, chop the top off and peel the black skin off and throw them in the blender with tomatillos and onion. (P.S. -Captain Wonderful opened the oven door a total of 170 times and told me he didn't think I was doing it right. After the 170th time, I could no longer take it and
told him the next time he opened the oven door that I was going to shove his ass in asked him if they taught him how to do it in Culinary School? He left and went outside and quit doing it).
