Prepare the candied lemon peel by placing the lemon strips, water, and sugar in a saucepan.
Gently bring to a boil, stirring until the sugar dissolves completely.
Reduce the heat and simmer for 30 minutes.
Remove from the heat and allow the peel to cool in the syrup.
Preheat the oven to 180°C (160°C fan) or Gas Mark 4.
Lightly butter a 25cm springform cake tin.
Trim the flan sponge to fit neatly into the base of the tin.
In a large mixing bowl, combine the golden caster sugar and cornflour.
Add the soft cheese and beat until smooth and creamy.
Gradually mix in the eggs.
Add the lemon zest, vanilla seeds, and crème fraîche.
Beat until the mixture is completely smooth.
Pour the filling over the sponge base.
Wrap the outside bottom third of the tin with foil to prevent leaks.
Place the tin inside a roasting tray.
Pour hot water into the roasting tray until it covers the base.
Bake the Lemon Cheesecake Recipe for 50–55 minutes, or until just set and lightly golden.
Check the water level halfway through baking and top up if necessary.
Remove from the oven and cool to room temperature for a softer texture.
Alternatively, chill for several hours or overnight for a firmer cheesecake.
Spoon the candied lemon peel and a little syrup over the top before serving.
