El Charro Salsa Para Tacos

INGREDIENTS:

16 oz can crushed tomatoes
1 cup tomato puree
1 cup water
1/2 medium white onion -- chopped
1/4 cup garlic puree -- *
1/2 cup oil
1/4 cup vinegar
4 tablespoons dried oregano
1 teaspoon salt -- or to taste

INSTRUCTION:

* Garlic Puree - peel 8 whole heads of garlic by smashing the cloves with the side of a wide knife; the peel will slip off easily then. Put the peeled garlic in a blender with about 2 cups of water, and puree. Drain, if necessary, and store in a tightly closed glass jar in the refrigerator.
Mix all ingredients. Taste and adjust seasoning. Can be served cold or hot.
