Make this shallot-brandy sauce to accompany our Beef Tenderloin with Mushrooms and Thyme.
Heat butter and oil in a large skillet over medium-high heat. Add shallots and garlic; cook, stirring often, until soft, about 5 minutes. Remove from heat; add brandy. Bring to a boil. Cook until reduced by half. Whisk in stock and cream and cook until thickened, about 10 minutes. Stir in thyme; season with salt and pepper.
