“XXX” Sauce

Directions

1. In a large, unoiled cast-iron skillet over high heat, char the roughly chopped onion and chiles by turning them over until the onion is evenly darkened on all sides and the dried chilies have blistered.
2. Add the whole tomatoes and peeled garlic cloves and continue to heat until darkened and blistered. Simmer after the tomatoes break, or about ten minutes.
3. Place all ingredients from the skillet into a blender and blend until smooth. Add salt to taste and serve.
