Fill a Moscow mule mug or large rocks glass with ice.
Add the gin, simple syrup, and lime juice to the glass. Stir with a bar spoon to combine.
Top off with ginger beer, garnish with a lime wedge, and serve immediately.
Notes
Simple syrup: You can buy simple syrup at the store, or make your own at home. Simply mix a 1:1 ratio of water and granulated sugar in a pot on the stove, bring to a boil and stir until the sugar dissolves, then let cool and store in a jar in the fridge.Serving suggestions: Gin mules are the perfect cocktail for dinner parties and holiday gatherings. Since you’ll only use a few ounces of ginger beer per drink, it’s easy to make a few of these at a time using just one can of ginger beer.You can spruce up this recipe for the holidays using flavored simple syrup, like making a flavored version for Christmas with cranberry rosemary simple syrup. Add fun garnishes like cranberries and fresh rosemary sprigs for a festive touch!
