Morita Salsa - La Tortilleria

Place chiles in hot water for 15 minutes to soften. Ensure they are kept under the water line by weighing them down with a bowl or saucepan. Once softened, drain and remove stems. To reduce spiciness, remove the seeds of the morita chiles before soaking.In the meantime, grill tomatoes, onion and garlic until black in many places.Put all ingredients in the blender and blend until smooth. Season to taste.
