To create a signature cocktail, simply recreate a classic cocktail on this bartender cheat sheet with your own spin. Here are a few examples: - Switch out the classic lemon or lime juice for another type of freshly squeezed citrus like orange or grapefruit. - Use an infused vodka rather than plain vodka. - Add some simple syrup (or a flavored simple syrup) to sweeten up the cocktail. - Shake in some marmalade to amp up the flavor in a fruity martini. - Use a different type of liquor than what's called for in the recipe.
