This Mess is ours
Pour boiling water of the hibiscus flowers in a dish. Allow to cool to room temperature then strain, pressing on the flowers to remove any liquid. Discard the solids.
Rim 2 double old-fashioned glasses with salt and fill with ice, set aside.
Fill a cocktail shaker with ice then add the tequila, St Germain, key lime juice, tea concentrate and simple syrup. Shake vigorously then strain the liquid. Fill to the top with ginger beer and garnish with a slice of key lime and a hibiscus flower.
