Add the vegetable oil, flour, and chili powder to a medium pot. Turn the heat on to medium and whisk the ingredients together. Continue to whisk as the mixture begins to bubble. Whisk and cook the mixture for one minute once it begins bubbling. After one minute, whisk in the water, tomato paste, cumin, garlic powder, and cayenne pepper until smooth. Allow the sauce to come up to a simmer. Once it reaches a simmer it will begin to thicken slightly. Starting with a 1/2 teaspoon, add salt to taste. I used about 3/4 teaspoon total. The sauce is now ready to use!.
