Apples, with their juiciness, tend to lend extra moisture to any cake or pastry they are incorporated into. Take, for instance, the likes of an apple cake with sliced apples on top or even apple crumble cheesecake with Choclairs. There are certain precautions you should take, especially for the latter prevent as less and moisture from escaping from the apples when they are being baked or cooked. Here are some troubleshooting tips.
Most recipes call for fresh apples, whether green or red, and in most cases, the recipes also call for the peel to be kept on. For such recipes, you must pat dry the apples well and, after slicing or dicing them, make sure you also get rid of the moisture that the apples might have on their surface. This will help in preventing the soggy texture, as apples also tend to release moisture during baking and after being cut into bits. To minimize this during the baking phase, cook the apples briefly with sugar and spices until they're softened. Cool them, then drain off any liquid before layering them on top of the cheesecake.
Most recipes call for prebaking the crust, but in case it doesn’t, we would highly recommend it to avoid the crust from becoming soggy. Also, make sure the crust is well-baked before pouring the cheesecake batter. A quick 10-12 minute bake at 180°C helps to set the crust, and this prevents it from absorbing too much moisture later. This works especially well when using Graham cracker, biscuit or cookie crusts.
For the extra causes, you can mix in a small amount of cornstarch or flour with the rest of the ingredients of your apple filling. This will help absorb any liquid released during baking and keep the topping from making the cheesecake soggy.
Some cheesecakes call for a water bath, and mostly those recipes might need to be baked at a slightly higher temperature to help set the cheesecake and the crumble faster. This is necessary so that it minimizes the time the crust and apple topping are exposed to moisture from the ingredients used. However, be careful not to overbake the cheesecake; you want it to set well but not dry out and start cracking.
Make sure that you measure out the ingredients carefully, especially the liquid ones, to avoid a runny batter. Stick to the recipe closely and use measuring cups, this is especially for ingredients like sour cream, for which make sure that and other moist ingredients are at room temperature. Make sure to mix them in carefully to avoid releasing excess moisture into the batter.
Once the cheesecake is baked, let it cool completely in the pan before removing it. Cooling it slowly prevents moisture from building up inside. After it has cooled, refrigerate it to set the cheesecake further.
If your apple cheesecake has a crumble topping, add it toward the end of baking, around the last 15-20 minutes. You can also add it after the cheesecake has cooled down. This prevents the crumble topping from becoming soggy during the longer bake time.
Using a springform pan with a parchment paper liner or a silicone baking mat can help with moisture control. This way, you can easily remove the cheesecake from the pan without it sticking, and any excess moisture that might form will not get trapped underneath. It also makes for a cleaner presentation when you serve it.
To prevent moisture from soaking into the crust layer the cooked apples between the crust and the cheesecake filling. This creates a barrier, ensuring that the apples don't directly touch the crust and thus prevent it from becoming soggy.
To avoid sogginess and to enhance flavor, you can spread a thin layer of fruit jam or preserves, such as apple or apricot, on top of the cheesecake layer before adding the crumble topping. The preserves create a slight barrier between the moist apple topping and the cheesecake, reducing the likelihood of moisture seeping into the crust.
