Preheat oven to 375 degrees F.
Wash and core tomatoes.
Fill pan with prepared tomatoes.
Tuck a garlic clove inside half of the tomatoes. Use more garlic for a stronger flavor, less garlic for a lighter taste.

Cook until tomatoes are soft and blistering; and garlic is fork tender.
Cool in pan for 10 to 15 minutes, or until easy to handle.
Drain in a colander for 10+ minutes.
Move the tomatoes and garlic to a blender or food processor and blend/process until desired smoothness.
Add the salt, pepper, and seasoning, blend, and taste test the results.
Continue adjusting seasonings and tasting until the desired level of flavor is reached.
Spoon the finished sauce into freezer containers.
Freeze for 9 to 12 months.
