One product we're really loving this summer is this jar of wild hibiscus flowers in syrup. They're meant to be added to a glass of white wine or champagne, and add a refreshing sweetness to the drinks.
Best of all, the flower is edible and can be used in other cocktail variations! The flowers come from Australia and can be found in specialty stores, or online. The product website lists a bunch of recipes here.
Buy it online at Amazon for $11.
