Before using edible flowers as a garnish or in a salad, spray them with a gentle stream of cool water in the sink, then carefully pat them dry with paper towels. Use immediately. Never eat flowers from a florist, a nursery, or a garden shop; they may have been sprayed. The same rule applies to flowers you find growing along a road or in a park.
The Crystallized Flower Company has taken garnish and pastry decorations to new heights. Desserts are made magical with crystallized blooms! Naturally grown, edible flowers are preserved in a recipe of sugar and meringue; essentially freezing them in time and turning them into candy.
