Spicy hibiscus can serve as a pretty cup for sorbet. A sugar coating gives flowers a showier, luminous look and also preserves them. Blooms with smooth, flat petals give the best results. Try pansies, violas and individual rose petals. To make your own, place flower stems in water while you assemble your materials in a cool, dry location.
Egg whites are the glue that makes the sugar stick to the flower.
Hold the flower with tweezers, and use a finger to coat flower with egg white, lifting petals to make sure flower has an even, thin coat. Lay flower face-down on the back of your hand and smooth with your finger to remove excess egg white. Pinch base with tweezers, and hold flower face up over sugar bowl. Sprinkle flower with sugar, and turn over immediately. Tap tweezers with spoon to release excess sugar.
