Heat butter in a frying pan on medium low heat. Add shallots and saute until they start to brown. Add garlic and cook 2 more minutes. Deglaze pan with vodka or wine. Cook out moisture. Add flour and cook 2 more minutes. Add lemon juice and stir in. A little at a time add cream and mix in, stirring constantly, until you have a smooth gravy like sauce. Add bouillon, cheese, and capers. Now here is my secret to the rich color of the sauce. Turn heat to low and let sauce sit on the burner.
