Ingredients
250g ginger biscuits
100g butter, melted
1 vanilla pod
600g soft cheese
125g icing sugar
284ml greek yoghurt
Method
1. Butter and line a 23cm loose-bottomed tin with baking parchment. Put 250g ginger 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.
2. Meanwhile, tip 25g of the sugar and the blueberries into a small pan. Mix the cornflour with 1 tbsp cold water and add this to the pan. Heat gently until the sugar dissolves. Increase the heat and bubble for 1-2 mins until saucy. Set aside to cool.
3. Remove the vanilla seeds from 1 pod: Slice the vanilla pod in half lengthways, 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.
4. 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 pot greek yoghurt and continue beating until the mixture is completely combined.
5. Now spoon half of the cream mixture onto the biscuit base, working from the edges inwards and making sure that there are no air bubbles. Now swirl in your cooled blueberries and pour the remaining mixture on top.
6. Smooth the top of the cheesecake down with the back of a dessert spoon or spatula. Leave to set in the fridge overnight.
7. Un-moulding and topping: Bring the cheesecake to room temperature, about 30 mins before serving. To un-mould, place the base on top of a can, then gradually pull the sides of the tin down. Slip the cake onto a serving plate, removing the lining paper and base.
