Remove the husks from one pound of tomatillos, rinse well.

Toss the tomatillos, onion, and seeded jalapenos in the olive oil and the salt.

Place on a large baking sheet.

Turn your broiler on high and broil until the vegetables become charred. (For me this was about 1 minute, then I flipped them over and broiled for 1 more minute). Watch very carefully and make sure not to burn.

Remove from oven and let cool.

Cut the ends off the onion and cut into into quarters, discard the outer layers.

Add the tomatillos, jalapenos, and the onion to blender along with cilantro, spices, and the juice of one lime and blend on high until smooth (30 seconds to 1 minute).
