My family has always browned the pork (I like bone in chops, cooking the bone in the chili makes it so delicious) and added the flour to the meat cooking it. I hate raw flour slurries. This method tastes way better (to me anyway) I dunno... I use chicken bouillon only if I accidentally added too much water to my chili as a last resort to save it lol chicken doesn't belong with pork. I noticed also that things like what kind of onions you use or tomatoes or powdered garlic vs fresh change the flavor of the chili. I'm not a big fan of tomatoes in chili. I prefer big in your face white or yellow onions. Sweet onions are too sweet. Fresh garlic, fresh fire roasted chili! And oh yeah, loose the cumin. Now thats good chili!
