A citrus cheesecake with a shortbread crust. It takes a long time of preparation but it is well worth the wait. If you can't find a vanilla bean, substitute 1/4 teaspoon vanilla extract for each 1 inch piece of bean. You can top with any of your favorite fruits or toppings, or eat it plain. Summertime fresh fruits are nice, or chocolate lovers can spread on a layer of fudge topping.
