Step 1

Place 4 cups of water in a medium saucepan, add the arbol peppers and cook at medium heat. Once the water starts to boil, add the tomatoes, tomatillos, and garlic clove.

Step 2

Cook the tomatoes, tomatillos, arbol peppers and garlic for 10 minutes, until they are well cooked, then set the saucepan aside. Allow the ingredients to cool at least 3-4 minutes.

Step 3

Once the ingredients have cooled, drain them and place in your blender along with the cilantro. Process this until you have a sauce with some texture. Pour it into a bowl and season with salt. Top with the diced white onion.
