Step 1

For chocolate crumb, preheat oven to 180C. Butter a 23cm springform cake tin and line the base with baking paper. Beat sugar and 170gm butter in an electric mixer until pale and creamy (1-2 minutes), then scrape down sides of bowl, add flour, cocoa and a pinch of salt and beat to combine. Roll out between 2 sheets of baking paper to 3mm thick, place on a baking tray, remove top piece of baking paper and bake until crisp (8-10 minutes). Cool, then break into rough pieces and process in a food processor to fine crumbs. Melt remaining butter, add to crumbs along with a pinch of salt and process to combine. Press evenly into base of prepared tin and bake until crisp (12-15 minutes). Remove from oven.

Step 2

Process cream cheese, ricotta, mascarpone, sugar, chocolate, eggs and orange rind in a food processor until smooth, pour onto crumb base and bake until set with a slight wobble in the centre (50 minutes to 1 hour). Allow to cool for 1 hour, then refrigerate until chilled (3-4 hours).

Step 3

Meanwhile, for roast cherries, preheat oven to 150C, combine ingredients in a roasting pan large enough to hold cherries snugly in a single layer, toss to combine and spread out evenly. Roast until syrupy and cherries are tender (6-8 minutes). Set aside to cool completely.

Step 4

Serve cheesecake topped with roast cherries, syrup and fresh cherries.
