Adjust the amount of sugar used in the rhubarb filling to suit your tastes. I prefer it more on the tart side, as I like the balance with the sweet cheesecake, however, this is not to everyone's taste.
When cooking the rhubarb down for the filling, make sure to reduce the liquid down enough to give you a thick, almost curd like consistency.
Press the biscuit base really firmly into the bottom of the pan to give a solid base for the filling. I use the end of my rolling pin to give me a flat surface to work with. A small glass, the back of a spoon or even clean fingers work just as well.
You can bake the cheesecake base. Baking the crust makes it firmer and less crumbly, so it completely depends on the texture you prefer. Once pressed into the tin, bake the crust for about 8 minutes at 180C/350F. Please make sure the base and tin are fully cool before topping with the cheesecake and rhubarb filling, or you will end up with a melted cheesecake puddle!
The cream cheese should be at room temperature before mixing. Using it at room temperature will ensure the cheesecake filling is smooth and creamy.
Take your time when layering the cheesecake and rhubarb together. Spreading the cheesecake layer gently over the rhubarb drizzle will allow the ripple layer to be effective in the end.
Have fun with the decorating of the top! You can create all sorts of patterns with the drizzled rhubarb and a skewer, so just a little bit of planning can result in some fabulous designs!
