It's really a simple recipe:
Halve tomatoes and place in glass baking dish
Dress with olive oil, garlic, onion, spices
Bake at 350-400 for about an hour, or until tomatoes begin to carmelize
Allow to cool before transferring to food processor
Process to desired consistency
Use now or freeze
The baked, smoky flavor of this tomato sauce is to die for.
