This is almost exactly like the recipe that I used to make from my Mom's "Joy of Cooking" cookbook, except that, as I recall, it didn't require any lemon at all. There are any number of cheesecake recipes, exotic, savory, etc. out there, but to me, nothing beats the "original" with sour cream topping. I sometimes put Cherry Pie filling on top, for Cherry Cheesecake. My children loved it that way. But, I'm a purist when it comes to cheesecake. And, frankly, forget that fluffy New York cheesecake. This dense and yummy one is the real deal in my book.
