Canned chipotle chiles are fully ripened jalapeños preserved in adobo sauce. They provide significant heat and smoky flavor. If you prefer less spice, use only 2 chiles and 1.5 tablespoons of sauce as suggested in the original source.
Chipotle chiles in adobo sauce can typically be found in the international foods aisle of large grocery stores or at Mexican markets.
To store leftovers, place in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave.
You can substitute the beef broth with chicken broth for a lighter flavor profile.
