Chilies vary greatly in heat units. One jalapeno will be hot and another will be mild. Both the same variety.
I like to use minced chilies in my pots. I can reduce the amount of other spices I use and create the spicy heat slowly as you eat. No sense blowing out the palate too soon in the meal. I still used good quality chili powder (several types), cayenne, cumin, onion and garlic powder, just less of it..
I also like some paprika (Hungarian) in there for color and flavor. Tasting as I go, I'll adjust for spice, salt, maybe add some molasses if it's too tomato'ee, always use dark chocolate and beer reduction...
I've written it down before but every batch is unique...this one I used cubed chuck tender fork roast. Kept the porky pig out cuz I brought a bowl for a guy at work who can't or won't eat pork!
