This cocktail features Amaretto, a sweet Italian liqueur made from apricot kernels. The recipe was first introduced in the 1970s as part of a brand promotion campaign. At our bar, we use a plant-based bitters as a substitute for egg white, offering a vegan-friendly twist. It’s a well-balanced sour cocktail where the rich sweetness of Amaretto and the aromatic notes of bourbon are perfectly brightened by a splash of lemon.
