Place the halved tomatoes in first, cut side up. Rip each basil leaf in half or thirds and place the pieces around the tomatoes. Place the whole garlic throughout the pan as well.
Drizzle with olive oil and sprinkle with salt and pepper to taste. Since I happen to LOVE pepper, I was pretty heavy with the pepper.
Roast in the oven for 1 hour. Remove and put all contents in the blender and puree until a semi even consistency. Before serving, taste!!! You may want more salt, pepper, fresh basil.
Makes 4 cups, freeze half if you can't eat that much in a week.
