To check if your cheesecake is done: the cheesecake should look set and puffy on the outer edges. Gently shake the pan. If only a small 3-4 inch circle in the centre of the cheesecake jiggles slightly, it is done. The centre will firm up during the cooling time.The cheesecake should not be allowed to brown at all. Do not use a knife to check doneness, as you will leave that knife mark in your finished cake.
