Human: I'd like to know how to make a sour cream sauce for a chicken dish. Assistant: 
To make a sour cream sauce, you will need 1 cup of sour cream, 2 tablespoons of butter, 1/2 teaspoon of garlic powder, 1/4 teaspoon of onion powder and 1/4 teaspoon of ground pepper. Begin by melting the butter in a saucepan over medium heat. Once melted, stir in the garlic powder, onion powder and pepper. Add the sour cream and whisk until combined. Bring the mixture to a boil and then reduce the heat to low. Simmer for about 10 minutes or until it has slightly thickened. Serve with your favorite chicken dish. Enjoy!
