Story Behind this Recipe
I think my family eats this meat sauce quite a bit ; Since it can be made with ketchup when you don't have tomato sauce, please try it out. Once you get the hang of it, it will be really easy.
After adding the flour, make sure to continue cooking gently while stirring, until no longer powdery. After all of the ingredients have been added, if the heat is too high it will burn, so keep your eye on it as it simmers.
