nothings very precise, and its mostly to taste but the important ingredients are good beer and the cocoa powder. I've made this without the meat, or without the beans, and I've done it in a slow cooker all day on low as well after browning everything.
about 2 - 3 lbs of stew meat (I like getting a mix of beef and turkey meat too)
2 cans of crushed tomatoes
3 cans of beans of choice (pinto or red)
1 bottle of beer
3 tbs unsweetened cocoa powder
2 or 3 big onions, chopped
2 or more jalapenos, minced (with or without seeds, as you like)
1 or more serrano chili peppers, minced (with or without seeds as you like)
garlic (as much as you'd like) minced.
to taste: cumin powder, cayenne pepper, paprika (not the sweet kind) and / or good chili powder
if you have it
(I usually use about a palmful of cumin, sprinkle of cayenne and paprika and maybe garlic powder)
Brown the stew meat and any other meat in batches in a heavy bottom pot (I usually used my pressure cooker, even tho I didnt pressure cook the chili)
Remove meat and add onions and cook until soft, add chili peppers and garlic, being careful not to burn garlic, just to soften the peppers and garlic.
Deglaze bottom of pot with the bottle of beer, scraping to get up all the meat and oniony goodness. Add in tomatoes, beans, cocoa powder, and other spices to taste, re-add the meat.
Combine all to mix well, bring to a simmer and cook until 'done'.
Serve with the usual chili fixin's -- cheese, sour cream, chopped onions, etc.
