The chili burned! It’s ok take a deep breath! If it has just stuck on the bottom of the pot and burned lightly, you will be fine. Don’t loosen anymore of the burned chili from the bottom, it could affect the flavor. Remove the pot from the stove and pour it into another pot, don’t scrape the burned bottom, put new pot on the stove and finish cooking. No one will ever know.
If you are making chili in a Crockpot add less beef broth as you will have less evaporation. You can make chili first thing in the morning before work and leave it in the Crockpot all day. Dinner will be ready to eat when you get home.
If the chili is to thin, crank up the heat and stir the chili more often until it reaches the right thickness, you can also toss in another can of black or red beans to help it thicken.
