Pro Tip: For a lighter twist on the Lemon Meringue Martini, skip the half and half. Instead, after shaking the other ingredients, prepare a frothy topping in a mixing bowl. Whisk one egg white with a teaspoon of sugar until it becomes light and frothy. Carefully spoon this airy mixture over your martini to add a visually appealing and fluffy layer that enhances both the flavor and texture of the drink.
