Today, July 30, 2014, is National Cheesecake Day. Cheesecake is a sweet dish consisting of one or more layers. The main, and thickest layer, consists of a mixture of soft, fresh cheese, eggs, and sugar. If there is a bottom layer, it often consists of a crust or base made from crushed cookies, graham crackers, pastry, or sponge cake. It may be baked or unbaked (usually refrigerated). An ancient form of cheesecake may have been a popular dish in ancient Greece even prior to Romans' adoption of it with the conquest of Greece. The earliest attested mention of a cheesecake is by the Greek physician Aegimus, who wrote a book on the art of making cheesecakes. I like the Jello NoBake Cheesecake that comes in a box!
