From the Blue Bloods Cookbook
There are two types of cheesecake in the world: coarse-textured Italian cheesecake made with ricotta cheese, and the smooth and creamy New York–style cheesecake made with cream cheese and sour cream. If you’re a New York Irish family, you go for the New York–style. Ours has a blue topping in honor of the NYPD and their uniforms—see below for the recipe.
This cheesecake is silky smooth with a melt-on-your-tongue texture. We make our crust with walnuts in addition to the classic graham crackers, which give it a crunchier, slightly more interesting taste and texture. The secret to a crack-free New York–style cheesecake is a water bath underneath the cake while baking. Bake it carefully, and this super-creamy dessert will look as beautiful as it tastes.
