The following recipe is very close to Dave Thomas' original chili recipe. Although the results give a slightly thicker chili, and slightly more spicier than what is available today from Wendy's. Try it yourself and compare the results
Chili Directions
Brown the round beef in a large kettle with at least 6 quart capacity. Once browned, drain off the liquid fat. Add the remaining ingredients and stir.
Bring to a boil, then reduce to a slow simmer. Cover the pan and continue to cook for 1 hour or so, stirring every 15 minutes.
