Notes
Chili powder - this recipe as written, calls for 4 tablespoons of chili powder and is mildly spicy. However, since not all chili powders are the same (some are stronger than others), I recommend you start with 2 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.No oregano? substitute with marjoram
Note: this recipe yields 4 cups of sauce; nutrition is calculated for one cup. It's unlikely anyone would consume a whole cup of sauce, so for more accurate nutrition info, divide by 4, allowing 1/4 cup sauce per person.
Divide by 2 for 1/2 cup per person.
Want it spicier? Add more chili powder and/or cayenne pepper?
Want it thicker? Add a flour slurry at the end: 1 cup warm water with 2-3 tablespoons of flour; whisk together, pour into sauce; cook a few minutes until thick
