assistant
To make a good sour cream sauce for potatoes, start by heating the butter in a large saucepan over medium heat. Once the butter has melted, add the flour and whisk to combine. Slowly add the milk while whisking continuously until all of the ingredients are fully combined. Add the sour cream, seasonings, and any other desired ingredients. Bring the mixture to a boil, then reduce the heat to low and simmer for 10-15 minutes or until thickened. Taste and adjust the seasonings if needed. Serve warm over your favorite potato dish. Enjoy!
