PRUNE AND APPLE TART

Wash and stone the prunes; peel, core, and slice the apples. Put them into a casserole, sprinkle in the sugar and the grated rind of the lemon.

Cover neatly with pastry, brush over the top with beaten egg, and bake in a hot oven for about three-quarters of an hour.

Sprinkle over with sugar and serve hot or cold.
