As light as the feet of the ballerina it was named after, this cloud-like meringue dessert is a showstopper in all categories. Make the meringue base ahead of time and wrap it tightly, keeping it at room temperature to assemble just before serving. Don’t feel like you have to stick to the recipe--add nuts, chopped sweet herbs, citrus zest or even chocolate to complement whatever fruit is in season. Feeling adventurous? Use the yolks from the eggs to make your own fruit curd. Potato starch makes this kosher for Passover.
