Aiming to create a drink that was refreshing and citrus-forward but with good body and structure, Henley bar lead Benjamin Rouse built on a base of blanco tequila for this recipe. "Rosé brings out the floral notes, and we balance the sweetness with agave syrup, which also brings out the earthy sweetness of the tequila without making the cocktail overpowering," says Rouse. "Egg white gives it a wonderful, velvety texture, and we top it with a bit of soda water for a slight effervescence.”
