This is my personal recipe, and it has won over 12 chili cook-offs, and I figured I'd share. It is a medium steak and bean chili. If I had to compare it, it would be similar to Steak N' Shake's chili, but better! It's rather involved, but trust me. Worth every minute! Try it. You will not be disappointed!
Placing steaks in freezer for about 15 minutes will stiffen them up and make them easier to cut.
To get bacon grease, cook about 4 slices of bacon in a skillet over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Remove bacon slices (save cooked bacon for another use). Retain about 1/4 cup of bacon grease; discard the rest, if any.
Use regular cola, not diet or caffeine-free.
You can serve immediately, but for best results, transfer into the insert of a slow cooker, and chill for at least 8 hours to overnight. (you can keep the chili refrigerated up to 48 hours if need be). When ready to serve, heat in covered slow cooker on High for about 3 hours; then set to Low for serving.
