Instructions
In a baking pan, low broil tomatoes in the oven until soft, about 5-7 minutes. Keep an eye on them!
Rotate them every couple of minutes so they are as even as you can get them.
A little blackened scorching of the skin is normal. This will give the tomatoes much better flavour than if you boil them in water! Trust me; broiling makes the difference!
Soften the chillies, garlic, and the onion on a dry cast iron skillet (NO OIL!). (We are using an iron comal in the photos.)
Salt to taste; not too much. You can always add a little more.
Place all the ingredients into your blender. Add just enough water to reach 3/4 of the way to the top of your ingredients in the blender; this will thin the salsa, so don't add too much water!
