If you do not have foil wide enough to wrap the pan with a single layer, simply skip this step and place the water bath on the lower rack beneath the cheesecake. It should create enough humidity to bake up a creamy cheesecake. You may need to drop the cooking time by 20 to 30 minutes. Do not over bake your cheesecake. Turn the heat off as soon as 1 to 2 inches of the outer edge is set. The center should remain wobbly.
