Limoncello Tiramisu

Lemon syrup:
125ml water
125ml sugar
1 lemon, peeled and juice
60ml limoncello

500ml whipping cream
60ml lemon juice
finely grated zest of 2 lemons
125ml + 60ml + 125ml lemon curd
190ml sugar
440g mascarpone cheese
2 packets ladyfingers (Boudoir biscuits)

For the lemon syrup:
Add the water and sugar to a small saucepan set over medium-high heat.
Stir until the sugar has dissolved.
Now simmer the mixture for 1 minute without stirring or fiddling with it.
Add the lemon peel and juice and simmer for 3 minutes.
Remove from the heat, strain through a sieve and set aside to cool.

Pour the cream into a mixing bowl and add the lemon juice, zest, 125ml lemon curd and sugar.
Whisk together with electric beaters until soft peaks form.
Add the mascarpone and mix on low speed until the mixture is fully incorporated and smooth. Set aside.
Pour the cooled lemon syrup and limoncello into a shallow dish.
Dip the ladyfingers in the mixture and lay them side-by-side in a 28cm x 22cm ceramic dish to form a compact layer.
Spoon half the mascarpone mixture on the biscuits and smooth it out.
Now spoon 60ml lemon curd on top and spread it out evenly.
Repeat the biscuit and mascarpone layers.
Spread the last 125ml lemon curd evenly over the top of the tiramisu.
Cover with plastic wrap and refrigerate overnight.
