This is as opposed to the Sweet Potato cheesecake using Italian dairy products. It is based on Galatoire’s cheesecake on the New York Times. Like most baking recipes here, I try to use my own sugar substitute, date jam, rather than any processed sugar. But if sugar is needed, as in the frosting, I use organic raw cane sugar. Most sugars are made from sugar beets, most of which are GMO in this country.
If you have graham crackers, just use a pie dough, 1/3 the size and use half of that for the bottom and the rest on the side.
