How to Make It
Heat a Dutch oven over medium-high heat. Add chorizo to pan; sauté 3 minutes or until browned. Remove chorizo from pan. Add half of beef to pan; sauté 5 minutes or until browned. Remove beef from pan. Repeat procedure with remaining beef. Add onion and garlic to pan; sauté 3 minutes.
Remove 4 chipotle chiles from can, and chop. Reserve remaining chiles and sauce for another use. Add chorizo, beef, chopped chiles, tomato paste, and next 6 ingredients (through ground cumin) to pan, and cook for 1 minute, stirring constantly. Stir in red wine, lime juice, beef broth, and tomatoes; bring to a boil. Reduce heat, and simmer for 1 hour, stirring occasionally.
Gradually stir in masa harina. Add pinto beans and black beans; bring to a boil. Cover, reduce heat, and simmer 30 minutes.
Look for masa harina, the corn flour used to make tortillas, in the Latin foods aisle at the supermarket, or substitute fine-ground cornmeal. Use kitchen shears to cut up the tomatoes in the can.
