The original Brunswick

Chill a coupe glass. Add 60ml zero-alcohol gin (such as Brunswick Aces Spades Sapiir), 15ml lemon juice, 30ml lemon oleo-saccharum, one tsp of marmalade and five drops of wonderfoam into a cocktail shaker. Shake hard for 10-15 seconds until cold and foamy. Double strain into coupe and garnish with a slice of dehydrated lemon or lime.
