Use cubed bottom round
brown in olive oil
while browning add Adobo chili powder, Cumin, good quality red chili powder, oregano salt, ground pepper, good paprika, cayenne to taste, [the Adobo has some heat], beef broth, Tomato sauce, Tomato fillets, simmer for as long as possible, don’t boil, stay away from goofy suggestions like Hershey bars, Root Beer, competition chili would disqualify you if you put beans in. The reason for seasoning while browning the meat is the meat gets a better infusion of chili flavor, adjust seasonings on the fly, can’t give you specific quanties as I don’t know how much you plan to make…make sure you don’t over salt, that’s a pot killer, the other seasonings are all adjustable, unless of course you dump a ton of cayenne in.
Good luck!
