Enchilada Sauce

Ingredients
1/4 cup vegetable oil
2 tablespoons self-rising flour
1/4 cup New Mexico or California chili powder
1 (8 ounce) can tomato sauce
1 1/2 cups water
1/4 teaspoon ground cumin
1/4 teaspoon garlic powder
1/4 teaspoon onion salt
salt to taste (I did not add any)

Directions
Heat oil in a skillet over medium-high heat.
Stir in flour and chili powder, reduce heat to medium, and cook until lightly brown, stirring constantly to prevent burning flour.
Gradually stir in tomato sauce, water, cumin, garlic powder, and onion salt into the flour and chili powder until smooth, and continue cooking over medium heat approximately 10 minutes, or until thickened slightly. Season to taste with salt.

To make self rising flour: Mix well 1 cup flour, 1 tsp baking powder and 1/4 tsp salt
