In a Moscow Mule, which ingredient is used as a splash?

In a Moscow Mule, lime juice is used as a splash to enhance the drink’s flavor profile. The cocktail traditionally includes vodka, ginger beer, and lime juice, with the lime juice providing a fresh, tangy note that complements the spiciness of the ginger beer and the smoothness of the vodka.

Lime juice is crucial for balancing the sweetness of the ginger beer and adds a necessary acidity that brightens the overall taste of the drink. When served in a copper mug, the elements of carbonation from the ginger beer and the sourness from the lime juice come together beautifully, creating a refreshing beverage that is both invigorating and satisfying.
