This is a recipe that I have made for years. It originally comes from the little recipe book that came with my Rival crockpot, but I have made many revisions to it, so it is quite abit different than the original. I am always picky about my spices, I believe in very good quality fresh spices and herbs, I always order my chili powder and cumin from a high quality spice company. Since I can not tolerate hot spice, I always use mild chili powder, but if you prefer hotter chili, feel free to heat it up with the hotter variety, just make sure it is fresh and good quality. Also the chocolate bar that is added is optional, but it makes a darker, richer and obviously more complex flavored sauce to the chili. I am sure this can also be made on the stove top, if you are so inclined. This is really delicious with Juniors cornbread, and pass the grated cheese and chopped onions please! This makes alot of chili, you can probably halve it if you have a smaller crock-pot.
