Found myself with extra Mezcal and a bottle of Bitter Truth Violet Liqueur. This is the result.
1oz Alipus Mezcal
.25oz Bitter Truth Violet Liqueur
.25oz Cocchi Americano Bianco
3 egg whites
.25oz St. Germain
Pinch Xantham Gum
Mix the Mezcal, Violet Liqueur, Cocchi, lime and simple and shake with ice. Double Strain and top with foam. The foam is made by combining egg whites, St. Germain, lemon, and Xantham gum in a whipped cream dispenser. The Xantham Gum is not required but helps to make the foam lighter. The foam recipe will make several cocktails.
