We've used this one for years:
North of the Border Chili
1/4 Cup olive oil
2 large yellow onions, chopped, about 4 cups
2 lb coarsely ground beef (shank, shoulder or chuck)
2 lb coarsely ground pork
salt
1/3 Cup mild, unseasoned chile powder
3 Tablespoons ground cumin, from toasted seeds, if possible
3 Tablespoons dried oregano, preferably Mexican
3 Tablespoons unsweetened cocoa powder (Yep, try it you'll like it)
2 Tablespoons ground cinnamon
1 1/2 tsp cayenne pepper, or to taste
4 Cup tomato juice
3 Cup beef stock or canned broth
8 medium garlic cloves, peeled and minced
2 Tablespoons yellow cornmeal as optional thickener (more as needed)
32 oz dark red kidney beans (drained and rinsed)
In a large skillet, over medium heat, warm the oil. Add onions and
cook, stirring occasionally, until tender, about 20 minutes.
Meanwhile in a 4 to 5 qt. heavy flameproof casserole or Dutch oven over medium heat, combine beef and pork. Season with 2 T salt and cook, stirring often, until meat has lost all its pink color and is evenly crumbled, about 20 minutes.
Scrape onions into casserole with meats. Stir in chili powder, cumin, oregano, cocoa, cinnamon and cayenne pepper. Cook, stirring, 5 minutes. Stir in tomato juice and beef stock. Bring to a boil
then lower heat and simmer, uncovered, for 1 hour.
Taste, correct seasonings and simmer another 30 minutes or until chili is thickened to your liking. Stir in garlic. To thicken chili further or to bind any surface fats, stir in the optional cornmeal.
Stir in the beans and simmer another 5 minutes.
Serves 6 or more. (We throw in a small hanful of crumbled chili peppers, but be careful)
