The Moscow Mule is a refreshing cocktail made with three main ingredients: vodka, ginger beer, and lime juice. Traditionally, it is served in a copper mug, which helps keep the drink cold and enhances its flavor. To prepare, fill the mug with ice, add 2 ounces of vodka, 1 ounce of fresh lime juice, and top it off with 4 ounces of ginger beer. Stir gently to combine. Garnish the drink with a lime wedge or mint leaves for added aroma and presentation. The Moscow Mule is known for its zesty and spicy taste, making it a popular choice for warm weather gatherings and celebrations.
