Take meat and chop into 3/8-inch cubes, removing all gristle and visible fat. Brown in an iron skillet, about 2 pounds at a time. Place in a large cast-iron chili pot, adding tomato sauce and equal amounts of water. Add chopped onion, garlic, jalapeno peppers (wrapped in cheesecloth) and chili powder. Simmer for 20 minutes
Then add the cumin, oregano, salt and cayenne pepper to taste. As moisture is required, add homemade beef stock until amount is used, then add water if needed. Simmer, covered, until meat is tender (about 2 hours), stirring occasionally. Then add the Masa Harina to thicken if needed. Add paprika for color.
Cook 10 additional minutes; correct the seasoning. Discard the jalapenos and serve. A small additional amount of cumin enhances aroma when added in the last ten minutes.
Servings: 20 to 25
