This cheesecake has a delicious nutty and crisp crust with a light but creamy citrusy filling. Recipe is from Gourmet (April 2008). Cheesecake can be made 2 days ahead and chilled, loosely covered. You can garnish with berries or julienned lemon zest. The cake needs to cool 2-3 hours before serving. If you don't have matzo cake meal, grind regular matzo meal (or even matzos) to a finer consistency in a food processor or blender.
