Sear beef in a large soup pot or cast-iron Dutch oven. You may need a little oil to prevent the meat from sticking. When the meat is all gray, add suet, chile peppers, and about two inches of liquid (you can use water, I use beer). Simmer for 30 minutes.
Add spices and garlic, bring just to boil; lower heat and simmer for 45 minutes. NOTE: Add more liquid only to keep the mix from burning. Skim off as much grease as you can, and add masa harina. Simmerfor another 30 minutes. Taste and adjust spices if necessary.
This is a spicy chili, so leave out some of the spicy stuff in the beginning if you have a tender tongue. At this point, I refrigerate the chili overnight which allows the chili to mellow and you can skim off all the grease.
* The masa adds a subtle, tamale-like taste, but it also thickens the chili. Masa Corn Mix is a tradition Mexican whole corn flour that is found in the baking aisle of most grocery stores (not to be confused with corn meal).
