A classic gin and tonic becomes a signature menu item with the unexpected flavor, color, and texture of a black-pepper-infused beet espuma. The finishing heat of the black pepper balances against the sweet earthiness of beets, complimenting the rosemary and juniper notes of the gin as well. This dynamic cocktail changes with every sip, as the espuma slowly infuses with the gin & tonic base, making each sip a new experience.
