With Passover, the biggest challenge is baking, as you cannot use flour or any raising agents. I found a terrific dessert in The Grain-Free Gourmet (Whitecap), by Jody Badger and Jenny Lass, written for people who have eliminated grains, gluten and refined sugar from their diets. Of course, it would be just fine for Easter as well.
Substitute oil for butter in this Passover dessert if you're serving it after a meat meal. Almond flour is available at bulk stores and some supermarkets.
