To eliminate or reduce the amount of cracking when baking cheesecakes:
Avoid over beating the cream cheese or beating the cream cheese at high speed. Over beating incorporates air into the batter, causing the cheesecake to puff up and then collapse.
Add eggs, one at a time, beating on low speed until just blended.
Provide a moist baking environment for your cheesecake by placing a small bowl of hot tap water on the bottom of the oven. The steaming effect created helps prevent burning and the drying out of the cake crumbs.
Avoid over baking. A cheesecake is cooked when the edges are slightly puffed and the centre is slightly soft and custard like.
Avoid opening the oven door during cooking. If you must open the door, open it towards the end of baking time and shut quickly but gently.
Always use the correct sized pan for the cheesecake mixture stated in the recipe.
