Chili powder - this recipe as written, calls for 6 tablespoons (or ¾ cup) of chilii powder and is mildly spice. However, since not all chili powders are the same (some are stronger than others), I recommend you start with 4 tablespoons of chili powder; once the other ingredients are added and the sauce has thickened, taste it for salt and seasonings. If you want it more spicy, add the remaining chili powder in ½ teaspoon increments, until you get the sauce to taste as strong as you like.
