A classic English shortcrust pastry, adapted from taste, with a hidden layer of raspberry jam, on top of which is a almond-flavoured cake and a topping of flaked almonds. It freezes well and makes a wonderful treat for afternoon tea.
- Make Sweet Shortcrust Pastry: Place flour, sugar, vanilla powder and butter in a food processor. Process until mixture resembles fine crumbs. Add yolk and iced water. Process until pastry just comes together, adding extra water if necessary. Turn out pastry onto a lightly floured surface. Knead gently until smooth. Shape into a disc. Wrap in plastic wrap. Refrigerate for 30 minutes.
- Grease and line a 28cm square springform pan. Press the pastry into the bottom of the prepared pan. Prick the base with a fork and refrigerate for 30 minutes.
- Preheat oven to 180C/350F. Line pastry case with baking paper. Fill with pie weights or uncooked beans and blind-bake for 10 minutes. Remove the beans and paper. Bake for 7 to 8 minutes or until base is light golden. Set aside to cool slightly. Spread the pastry case with raspberry jam, leaving a 1cm gap around the edge. Reduce oven temperature to 160C/320F.
- Cream butter, raw sugar and vanilla powder until light and fluffy. Beat in eggs, one at a time. Beat in almond meal, spelt flour and baking powder. Spread the filling over the jam and sprinkle with flaked almonds.
- Bake for about 40 minutes until nicely golden brown and the filling is just firm to the touch. Stand in pan to cool completely. Cut into slices and serve.
