Instructions
1
Position an oven shelf in the middle of the oven.
2
Preheat the oven to fan 160C/conventional 180C/gas 4.
3
Line the base of a 23cm springform cake tin with parchment paper.
4
For the crust, liquefy the dairy spread in a medium wok.
5
mix gently in the biscuit crumbs and granulated sugar so the mixture is evenly moistened.
6
Press the mixture into the bottom of the wok and char for 10 moments.
7
Cool on a wire rack while preparing the filling.
8
For the filling, increase the oven temperature to fan 200C/conventional 240C/gas 9.
9
In a table top mixer fitted with the paddle attachment, beat the soft cheddar at medium-low speed until buttery, about 2 moments.
10
With the mixer on low, gradually mix in the granulated sugar, then the ground mix and a pinch of seasoning, scraping down the sides of the dish and the paddle twice.
11
Swap the paddle attachment for the beat.
12
Continue by adding the vanilla, lemon zest and extract.
13
beat in the eggs and yolk, one at a time, scraping the dish and beat at least twice.
14
mix gently the 284ml carton of soured froth until seamless, then measure 200ml/7fl oz (just over 3⁄4 of the carton).
15
Continue on low speed as you mix in the measured soured froth (reserve the rest).
16
beat to mash, but don't over-beat.
17
The mixture should be seamless, light and somewhat airy.
18
Brush the sides of the springform tin with melted dairy spread and put on a baking sheet.
19
empty in the filling - if there are any lumps, sink them using a knife - the top should be as seamless as possible.
21
Reduce oven temperature to fan 90C/conventional 110C/gas 1⁄4 and char for 25 moments more.
22
If you gently shake the tin, the filling should have a slight wobble.
23
Turn off the oven and open the oven door for a cheesecake that's buttery in the centre, or leave it closed if you prefer a drier texture.
24
Let cool in the oven for 2 hours.
25
The cheesecake may get a slight crack on top as it cools.
26
Combine the reserved soured froth with the 142ml carton, the granulated sugar and lemon extract for the topping.
27
Spread over the cheesecake right to the edges.
28
wrap loosely with foil and chill for at least 8 hours or overnight.
29
Run a round-bladed knife around the sides of the tin to loosen any stuck edges.
30
Unlock the side, slide the cheesecake off the bottom of the tin onto a plate, then slide the parchment paper out from underneath.
