* You can make this sauce as hot as you want by adding up to a total of 4 dried Chipotle chiles.
Cover chilies with warm water. Let stand until softened, about 1 hour. Drain and finely chop. Cook and stir bacon and onion in a 2-quart saucepan until bacon is crisp; stir in chilies and remaining ingredients. Makes about 4 cups sauce.
