Cutting Flowers: If you are cutting your own flowers, cut them as close to the base of the flower as possible.
Washing Flowers: Carefully and gently wash (under slow running cool water) and completely dry the flowers or petals. Place washed flowers on paper towels to dry, gently blot the flowers if necessary to remove excess water.
Egg White Mixture: Beat the egg white in a small bowl until slightly foamy, if necessary add a few drops of water to make the white easy to spread. You want to completely break the albumen down so you don't get any jelly-like clumps on your flowers, just a smooth coat of white. If using powdered egg whites or meringue powder, in a small bowl, combine powdered egg whites or meringue powder with water, using the amounts shown on the containers.
Painting the Flowers: Holding a flower or petal in one hand (tweezers help here), dip a small paint brush into the egg white. With the other hand, gently paint each flower or petal individually with beaten the egg white. Start by coating the back-side of the petals, then turn over and coat the top-side of the petals. C over the flower or petal completely, but not excessively.
When thoroughly coated with egg white, hold the flower or petal over the sugar dish and gently sprinkle with superfine sugar evenly all over on both sides. If the sugar is absorbed after a few minutes, sprinkle again. Gently shake off any excess sugar.
Drying the Flowers: Place the coated flowers or petals on wax paper on a wire rack to dry. Let dry at room temperature (this could take 12 to 36 hours).
Repeat process with the remaining flowers or petals.
To test for dryness, check the base of the bloom and the heart of the flower to make sure they have no moisture. Flowers are completely dry when stiff and brittle to the touch. To hasten drying, you may place the candied flowers in an oven with a pilot light overnight, or in an oven set at 150 degrees to 200 degrees F. with the door ajar for a few hours.
Storing the Flowers: Store the flowers in layers, separated by tissue paper, in an airtight container at room temperature until ready to use. This crystallized/candied flowers can last up to one (1) year if properly stored.
