EQUIPMENT: One loose-bottomed tin, baking parchment, plastic food bag, rolling pin, large bowl, dessert spoon, chopping board, kitchen knife, electric mixer, spatula, serving plate, blender or food processor, sieve
Make the base: Butter and line a 23cm loose-bottomed tin with baking parchment. Put 250g digestive biscuits in a plastic food bag and crush to crumbs using a rolling pin. Transfer the crumbs to a bowl, then pour over 100g melted butter. Mix thoroughly until the crumbs are completely coated. Tip them into the prepared tin and press firmly down into the base to create an even layer. Chill in the fridge for 1 hr to set firmly.
Remove the vanilla seeds from 1 pod: Slice the vanilla pod in half length ways, leaving the tip intact, so that the two halves are still joined. Holding onto the tip of the pod, scrape out the seeds using the back of a kitchen knife.
Make the filling: Place 600g soft cheese, 100g icing sugar and the vanilla seeds in a bowl, then beat with an electric mixer until smooth. Tip in 284ml double cream and continue beating until the mixture is completely combined. Now spoon the cream mixture onto the biscuit base, working from the edges inwards and making sure that there are no air bubbles. Smooth the top of the cheesecake down with the back of a dessert spoon or spatula. Leave to set in the fridge overnight.
