Step 1

Grease and line a 20cm/8in springform tin with baking paper.

Step 2

Crush the biscuits in a freezer bag and bash with a rolling pin until they are reduced to sand-like crumbs – alternatively pulse the biscuits in a food processor. Pour the melted butter into a mixing bowl, add the biscuit crumbs, cinnamon and cardamom and mix to thoroughly combine. Firmly press the crumbs into the base of the prepared tin and flatten into an even layer using the back of spoon or base of a flat-bottomed glass. Chill for 30 minutes while you prepare the filling.

Step 3

Melt the white chocolate in a heatproof bowl over a saucepan of barely simmering water, remove from the heat and leave to cool slightly. Soak the gelatine leaves in a bowl of cold water for 5 minutes until soft and floppy.

Step 4

In a large mixing bowl, beat together the cream cheese, caster sugar, vanilla and lime zest until smooth and creamy. Add the mango purée, melted white chocolate and half of the double cream and whisk until smooth and thoroughly combined.

Step 5

Heat the remaining cream until just boiling (either in a heat-proof jug in the microwave or a small saucepan over a medium heat). Drain the gelatine leaves, squeezing out any excess water, add to the hot cream and whisk until melted. Pour into the cheesecake mixture and whisk to combine.

Step 6

Spoon the mixture onto the chilled biscuit base, spread level and tap the tin on the work surface to knock out any large air bubbles. Cover and chill for at least 4 hours, but preferably overnight, until set.

Step 7

To make the topping, soak the gelatine leaf in cold water for 5 minutes until soft and floppy. Pour half of the mango purée into a bowl, add the lime juice and 2 tablespoons cold water. Heat the remaining mango purée until just below boiling and remove from the heat. Drain the gelatine, squeeze out any excess water and add to the hot purée. Whisk until the gelatine has melted and then add the purée and lime mixture. Whisk to combine and then pour over the top of the cheesecake in an even layer. Return to the fridge for a further 30 minutes–1 hour until set.

Step 8

Carefully remove the cheesecake from the tin and peel off the baking paper. Arrange the mango slices on top and serve.
