What I consider my best pot of chili had 3 meats one was a thin sliced beef like carne asada meat. The second was a chuck roast. and the third was hot Italian sausage. All of which were cut into chucks. For spices I used 3 different chili powders, crushed red pepper, white pepper, cracked black pepper, salt, and some garlic powder. All goes into a big pot to which I add several cans of dark red kidney beans, a diced onion, cut celery, bell pepper, jalapenos, and a can or two of crushed tomatoes, I'll sometimes add a can of tomato sauce. I slow cook it on a low simmer stirring frequently. I'll start it cooking in the morning and spice to taste as the day progresses. By dinner time it is done but the next day is even better.
Nothing in the above is actually measured as I have been cooking chili for so long I know what I want to accomplish. I cook by looks and taste. I believe if chili doesn't make your head sweat it isn't chili. If I'm cooking for a gathering (rare) I will split some of it off about halfway through into another pot and respice it.
