*The meringue nests and orange curd can both be prepared ahead of time, and stored for 2-3 days separately, but don't assemble the nests until you are ready to serve. *Store the meringues in a cool, dry place. Humidity will cause them to become soft and sticky. I made these the night before, and just left them uncovered in the oven. It was perfect for keeping them arid and crisp.
