1. Melt the butter in a large saucepan. Remove from the heat and stir in the crushed biscuit crumbs. Press in an even layer over the base of a 20cm loose-based cake tin or deep flan dish. Transfer to the refrigerator and chill for at least 20 minutes.                                                                                                       
2. Meanwhile, pour 60ml of just-boiled water into a measuring jug. Sprinkle in the powdered gelatine, stirring to disperse. Leave to dissolve completely for 10-15 minutes, stirring occasionally. When the liquid is clear, stir in the elderflower cordial.                                                                                                     
3. Beat the cream cheese and Tate & Lyle Golden Caster Sugar together until softened, then fold in the marmalade. In a separate bowl, whip the cream until thick, but not stiff. Fold into the cream cheese mixture with the finely grated lemon zest, using a large metal spoon or rubber spatula - do not beat at this stage.                                                                                           
4. Pour the cooled gelatine liquid into the mixture in a thin, steady stream, stirring whilst you do so. Make sure that it is thoroughly incorporated. Pour over the chilled biscuit base. Cover and refrigerate until set - about 2 hours.
5. Carefully remove the cheesecake from the cake tin. Decorate with whipped double cream, lemon slices and a few mint leaves. Just before serving, spoon the warmed marmalade on top.
