Ingredients

1 1/2 tablespoons extra-virgin olive oil 

1/2 Spanish onion, finely chopped 

2 garlic cloves, minced 

1 can (28-ounces) crushed tomatoes 

1 canned chipotle chile, packed in adobo sauce, minced 

1 1/2 tablespoons Worcestershire sauce 

1 1/2 tablespoons cider vinegar 

1/4 cup unsulfured  molasses 

Juice of 1/2 lemon 

Coarse salt and freshly ground black pepper 

Preparation

In a medium saucepan, heat oil over medium heat. Add onion and garlic. Cook, stirring, until onion is soft and translucent, about 5 minutes.

Stir in tomatoes, chile, Worcestershire, vinegar, molasses, and lemon juice. Simmer over medium-low heat until reduced by a fourth, stirring occasionally, about 45 minutes.

Working in batches, purée sauce in a blender. Season with salt and black pepper. Refrigerate in a jar up to 2 weeks.
