Sweet Shortcrust Pastry Tart Case:
Blend flour, baking powder and butter in a food processor until fine crumbs form. Combine egg and sugar and add to the flour, blending briefly until the mixture just forms a ball. Turn out onto a floured surface and knead lightly until smooth. Roll out between baking paper to 2mm thickness and line a 30cm flan tin with removable base. Prick well with a fork and refrigerate for at least 15 minutes. Bake at 200C for 20 minutes until a light golden colour. Allow to cool and use as required.
Note: this pastry can shrink when cooked if stretched during handling, so take care to handle gently when lining the tin.
