1. Prepare the Pan:
* Lightly grease and line a 20cm x 20cm (8-inch x 8-inch) square baking tin with baking parchment, leaving some overhang on two sides to make it easier to lift the cheesecake out later. This small detail makes a big difference!

2. Make the Biscuit Base:
* Place the digestive biscuits into a food processor and blitz until they form fine crumbs. Alternatively, put them in a sturdy resealable plastic bag and crush them with a rolling pin – a great way to release some stress!
* Transfer the biscuit crumbs to a medium bowl. Pour in the melted butter and mix thoroughly with a fork or spatula until the crumbs are evenly moistened and resemble wet sand.
* Tip the buttery crumbs into your prepared baking tin. Press them down firmly and evenly using the back of a spoon or the base of a clean glass. Ensure you get into the corners for a neat finish.
* Place the tin in the refrigerator to chill for at least 30 minutes while you prepare the filling. This helps the base to firm up.

3. Prepare the Turkish Delight:
* Take your 200g of Turkish Delight for the filling. If it’s very sticky, lightly dust your knife and chopping board with a little icing sugar to prevent sticking. Chop it into small, bite-sized pieces, around 1cm cubes. Set aside. If you’re using extra for the topping, chop that now too and keep it separate.

4. Make the Cheesecake Filling:
* In a large mixing bowl, beat the room temperature full-fat cream cheese with an electric mixer (or a stand mixer fitted with the paddle attachment) on medium speed until smooth and creamy. Scrape down the sides of the bowl to ensure everything is incorporated. It’s crucial the cream cheese has no lumps.
* Add the sifted icing sugar, rosewater, and vanilla extract to the cream cheese. Beat again on low speed until just combined and smooth. Be careful not to overmix at this stage. Taste the mixture – if you prefer a stronger rose flavour, you can add another ¼ teaspoon of rosewater, but do so cautiously as it can become overpowering.
* If using, add a few drops of pink food colouring and mix gently until you achieve your desired shade. A pale, delicate pink looks beautiful.
* In a separate, clean bowl, whip the cold double cream using an electric mixer until it forms soft to medium peaks. It should hold its shape but still be light and airy. Don’t overwhip it to stiff peaks, or the cheesecake might become too dense.
* Gently fold about one-third of the whipped cream into the cream cheese mixture using a spatula to lighten it. Then, fold in the remaining whipped cream in two more additions, being careful not to knock out too much air. The goal is a smooth, voluminous mixture.
* Finally, gently fold the chopped 200g of Turkish Delight pieces into the cheesecake filling until they are evenly distributed.

5. Assemble the Cheesecake:
* Remove the chilled biscuit base from the refrigerator.
* Carefully spoon the Turkish Delight cheesecake filling over the biscuit base.
* Spread the filling evenly using an offset spatula or the back of a spoon, ensuring it reaches all corners and the surface is as level as possible.

6. Chill to Set:
* Cover the baking tin loosely with cling film (plastic wrap), making sure it doesn’t touch the surface of the cheesecake.
* Transfer the cheesecake to the refrigerator to chill and set for at least 6-8 hours, but preferably overnight. This dessert cannot be rushed; proper chilling time is essential for it to firm up enough to slice cleanly.

7. Decorate and Serve:
* Once the cheesecake is fully set, carefully lift it out of the tin using the overhanging baking parchment.
* Place it on a cutting board. Before slicing, you can decorate the top. Sprinkle over the extra chopped Turkish Delight, chopped pistachios, and a few edible dried rose petals if using.
* For neat slices, use a large, sharp knife. Dip the knife in hot water and wipe it clean between each cut.
* Cut the cheesecake into squares or slices of your desired size. A 4×4 grid will give you 16 generous portions.
* Just before serving, you can give it a final light dusting of icing sugar for a touch of snowy elegance.
