To candy edible flower petals, select clean petals that have sufficient size to be candied, such as rose petals. Moisten the petals with an egg white wash made by beating or whisking an egg white. The wash can be applied with a soft bristled brush to the delicate petals or the entire flower. The petal can then be dipped into, wiped, and/or sprinkled with super fine sugar. Remove the excess from the petal by gently shaking the petal. Lay the petal on wax paper and allow it to dry thoroughly, which may take 4 to 8 hours. The candied petals can now be used with desserts, sorbets, beverages, toppings, butters, spreads, and other foods.
