Make Ahead Tip: Cover and refrigerate for up to 3 days or freeze for up to 2 months.
Ingredient Note: Chipotle peppers are dried, smoked jalapeño peppers. Ground chipotle chile pepper can be found in the specialty spice section of most supermarkets. Chipotle chiles in adobo sauce are smoked jalapeños packed in a flavorful sauce. Look for the small cans with the Mexican foods in large supermarkets. Once opened, they'll keep up to 2 weeks in the refrigerator or 6 months in the freezer.
Shopping tip: Boston butt (or “Boston-style butt,” “fresh pork butt,” “pork shoulder”) can weigh upwards of 10 pounds, so you may have to ask your butcher to cut one down for this recipe.
