Two 28-ounce cans diced tomatoes with their liquid
2 cups water
3 bay leaves
1/4 teaspoon crushed red pepper
1 teaspoon sugar
Kosher salt and freshly ground black pepper
In a large saucepan, heat the olive oil. Add the garlic and cook over moderate heat, stirring, until golden, about 2 minutes. Add the diced tomatoes and their liquid, the water, bay leaves, crushed red pepper and sugar. Season with salt and bring to a boil. Reduce the heat to low and simmer, stirring occasionally, until slightly thickened, about 45 minutes. Discard the bay leaves.
Working in batches, puree the sauce in a blender. Transfer to a bowl and season with salt and pepper.
The sauce can be refrigerated for up to 5 days or frozen for up to 2 months.
