How to make the Cherry Green Creme de Menthe Royal – Cherry Green Creme de Menthe Royal was contributed and created by Aaron Turpin on Christmas Eve several years ago, from a limited ingredient list. It tastes just like regular Green Creme de Menthe only better.In a large, Milkshake-shape glass (16-oz), pour the Vodka, Cherry Juice, 3 Cherries, Green Creme de Menthe and cold Milk. Stir the Mixture carefully with a chopstick being careful not to spill until the Syrup has dissolved. Add a flexible straw. Top with Whipped Cream from a can. Garnish with Green Creme de Menthe sprinkles and one of the Cherries, and serve immediately.
