By danyell923

Ingredients

• 1 tablespoon unsalted butter
• 1 tablespoon vegetable oil
• 1 1/2 cups chopped onion
• 4 garlic cloves, minced
• 1 serrano chile, minced
• 1 cup ketchup
• 1 cup brewed espresso
• 1/4 cup distilled white vinegar
• 3 tablespoons unsulfured molasses
• 2 teaspoons chile powder
• 1 teaspoon kosher salt
• 1 teaspoon sugar
• 1/4 teaspoon Worcestershire sauce

Preparation

Step 1

In a large saucepan, melt the butter in the oil. Add the onion, garlic and serrano and cook over moderately low heat, stirring occasionally, until the onion is softened, about 8 minutes. Stir in all of the remaining ingredients and bring to a simmer. Cover and cook the sauce over low heat for 30 minutes, stirring occasionally.

Scrape the sauce into a food processor and puree until smooth. Transfer to a bowl and let cool, then cover and refrigerate overnight to allow the sauce to mellow.
