Easy No-Lump White Sauce

In a small saucepan over medium heat, heat milk until warm. Do not boil.

In a separate bowl, mix the flour and oil together, then add a small spoonful of the warmed milk at a time, whisking until the mixture is runny and smooth.

Over medium heat, heat the entire mixture, whisking constantly. Turn off the heat at desired consistency. You can add anything to it, e.g., cheese, salt & pepper, parsley, garlic, chilli.
