Ingredients

4 plum tomatoes
2 jalapeno (or Serrano) peppers
1 garlic clove
1/2 white onion
1 to 2 Tbsp cilantro
1 tsp. salt
1/4 tsp. pepper
1/2 tsp. cumin
1/4 tsp. chili powder
1/2 lime

Directions

1. In the broiler, roast the tomatoes, peppers and garlic clove (with papery skin) for 3 to 6 minutes per side. It should be enough to brown, but not burn, the sides.^*
2. In a blender add spices, chopped onions (rinsed well before adding to blender), peppers, finely chopped garlic and cilantro. If you blender can handle it, chop the ingredients in the blender.
3. Remove skin from tomatoes and pepper and add to the blender.
4. Blend thoroughly and add the limejuice.
* Irma suggested wrapping peppers in aluminum foil for easier broiling. I suggest that you wrap the peppers and the garlic in foil and broil along with the unwrapped tomatoes (3 to 6 minutes per side).
