Melt the butter in a small saucepan and take it off the heat.
Blitz the vanilla biscuits to fine crumbs, stir them into the butter and divide the biscuit mixture between 8 serving glasses. Do not press it down – it should just sit in a nice, even layer.
Risalamande cheesecake
Put the cream cheese, whipping cream, vanilla seeds and icing sugar in a bowl and whisk until the cream thickens. It helps to rub the vanilla seeds together with a little of the icing sugar first – that makes them easier to whisk in evenly.
Then fold the rice pudding and chopped almonds into the cream, and taste to see whether you would like it sweeter.
Spoon the cheesecake cream into a piping bag – it is easier to control that way – and pipe it into the glasses.
Top with orange curd, a few slivered almonds and, if you like, a sprinkling of edible gold flakes.
