Citrus Cream Cheese Icing
In this icing, the acidity of the citrus enhances the tanginess of the cream cheese. Orange, lemon, and lime all work well. Although the orange icing is my favorite, lemon is especially flavorful with fruity vanilla cakes, such as the Blueberry “Cheesecake” (page 123), and the lime icing spread over a vanilla cupcake and sprinkled with graham cracker crumbs, or sandwiched between two homemade graham crackers (see Graham Cracker Dough, page 86), can evoke a Key lime pie.
