Ok, this is my new favourite dessert! Crisp pastry with a layer of lush fresh raspberries and nuts, covered in creamy white chocolate - I'm in love! This has been adapted from 'The Chef's Table' and is really easy to put together. You can make the tart case in advance and then fill it 4-5 hours before serving. The recipe makes a 10" tart, but I have made a smaller one (8") by halving the filling, I made an extra tart case with the left over pastry and saved it for another day. Please see additional notes at end.
