1 tablespoon shallots, minced
1 teaspoon garlic, minced
1/2 bottle Worcestershire sauce
2 ounces Jack Daniels whiskey
4 ounces cold butter
1 teaspoon fresh parsley, chopped

Saute shallots and garlic in a small amount of oil or butter. Add to Worcestershire sauce and simmer until reduced by half. Add black pepper and whiskey. Ignite to burn off alcohol. Remove from heat and whisk in cold butter until mixed.
