White Chocolate and Raspberry Cheesecake

This cake made me many, many friends! It is simply the most amazing cheesecake in the world. Will get around to posting the recipe some day but . . Wow. Despite the expense of good raspberries in winter this is what my husband is getting off santa. Okay, may regret this but here's the recipe:

Ingredients

For the base

85g digestive biscuits, crushed (Americans, graham crackers. I usually use 100g of each for the base cause I like a little bit more)
85g ginger nut biscuits, crushed
85g unsalted butter, melted
For the filling
500g, white chocolate, broken into pieces
50g unsalted butter
1/2 vanilla pod, split lengthways
500g full fat soft cheese
50g caster sugar

175ml double cream
225 g punnet fresh rasberries, plus extra to decorate

Directions

   For the base, combine biscuits & butter, then press into the base of a 23cm (9.5") springform tin.
   
   
   
2. 
   
   For the filling, put the chocolate, butter and vanilla pod in a heatproof bowl and microwave in 20-second bursts to melt it. Allow to cool slightly.

   In another bowl, mix the soft cheese, sugar and whipping cream til smooth.
