How to Make Enchilada Sauce

Matt made an awesome enchilada sauce that we used tonight, based on the following recipe from About.com.

Ingredients:
2 tbsp vegetable oil
2 tbsp flour
2 tbsp chili powder
1/2 tsp cumin
1/4 tsp cayenne pepper, or to taste
2 cups water
1 8 ounce can tomato paste
1 tsp garlic powder
1/2 tsp onion powder
1/2 tsp salt

Preparation:
Heat the oil, flour and chili powder together in a large pot.

Allow to cook for a minute or two.
Add the remaining ingredients and bring to a slow simmer.

Stir well to combine and dissolve tomato paste in water.

Allow to cook for at least 20 minutes, stirring occasionally.

Add more spices as desired.
