To make a good sour cream sauce for potatoes, start by heating up some butter in a saucepan over medium heat. Once the butter is melted, add in 1/2 cup of flour and stir until it's lightly toasted. Next, whisk in 2 cups of milk and bring to a boil. Reduce the heat to low and simmer for about 5 minutes or until the mixture has thickened. Finally, stir in 1/4 cup of sour cream and season with salt, pepper, and any other desired herbs or spices. Serve your homemade sour cream sauce over hot potatoes for an easy and delicious side dish!
