About this recipe:This easy no-bake cheesecake is creamy, smooth and tangy. Simply leave in the fridge for longer if you prefer a more solid filling. I used homemade lemon curd for the topping (it's very simple to make and absolutely delicious if you don't mind a bit of stirring). I'm sure shop-bought lemon curd would also be very nice.
mixed nuts (I used hazelnuts, brazil nuts and walnuts)
For the filling
1 (284ml) pot double cream
200g caster sugar (vary depending on preference)
zest, and juice of half a lemon
Lemon curd topping
zest and juice of 2 1/2 lemons
220g caster sugar
55g unsalted butter

Put the digestive biscuits and nuts (if using) into a bag and bash with a rolling pin into crumbs. Melt the butter and brown sugar in a saucepan and when melted mix with the biscuits/nuts. If you find they are not well coated, melt more butter and add this. When the biscuit mixture is well coated press into a deep 23cm (9 in) round cake tin. Place in the fridge to cool.
Whisk together the mascarpone, lemon zest and juice and caster sugar. Whisk the double cream in a seperate bowl to form firmish peaks. Add the double cream to the cheese mixture, whisk until smooth. Pour the cheese mixture onto the biscuit base and smooth with a spatula. Put in the fridge for 1-2 hours.
If you want to make your own lemon curd, do this while the cheesecake is setting: Add the butter and sugar to a glass bowl and place this over a pot of simmering water. Once the butter has melted add the lemon zest and juice (I like to well squeeze the lemons). Keep stirring until mixed.
Beat together the eggs and slowly add these to the glass bowl stirring constantly but not too fast.
Now.. keep stirring for around 30-40 minutes. Eventually the mixture will thicken and the spoon will leave a trace through the mixture allowing you to see the bowl. If unsure just keep going for a little longer.... it shouldn't do any harm.
Empty into a container and allow to cool. (Do not add to cheesecake while hot.)
After 1-2 hours you can add the curd to the cheesecake. Smooth over and allow to set for another 2 hours for a soft filling or leave in overnight if you have the time. Keep refrigerated. I couldn't help trying the cheesecake after 2 hours... its was very soft but I find that delicious! I have just had another piece after being in overnight and it is completely firm. Your choice.
When making any non bake cheesecake, I tend to find that digestive biscuits are the best option avalible, they have the right texture and how you would expect the base to look. If you want the best result but want a bit more omffhh use chocolate digestives - 25 Jul 2011
