This recipe is for a basic shortbread dough. Shortbreads normally finish up as biscuits or cakes. With this recipe, I am using the dough to line flan or tart cases. A good fresh raspberry flan, or strawberries, peaches or Summer fruits on a shortbread pastry case is delicious. Put the raw fruits directly on the shortbread or spread clotted or extra-thick cream on the base and arrange all the fruits on top.
