Light Mexican Tomato Sauce: Caldillo De Jitomate - cooking recipe

Ingredients

2 roma tomatoes
1 slice onion, a 1 1/2 inch piece is good
1 -2 dried arbol chile (or 1 fresh serrano, 1/2 fresh jalapeno, or 1 dried guajillo)
salt, to taste

Preparation

Place the tomatoes, onion and chiles in a small sauce pan with enough.water to almost cover the tomatoes. Cook until the tomatoes are soft. Then puree them in a blender with salt to taste and some of the cooking liquid, adjusting the amount to achieve the texture that you like.
Some people add a little powdered chicken stock (Knorr Suiza). You can add a bit of garlic too. If you are pouring this over fried eggs you can either pour it over them in the same pan where they cooked and let the sauce simmer a little or you can just pour it over the eggs right in the serving plate (I prefer this method-less fat!). You can also use this sauce for chilaquiles, but in this can be fried in a little oil or added to the fried tortillas in the pan where they were fried. I like my chilaquiles crunchy so I fry the sauce separately in about a tsp of oil.
This sauce is so basic that herbs such as oregano or cilantro can be added and the flavor can be changed completely.
