Line a deep pudding-dish with slices of buttered bread. Fill this with alternate layers of whortleberries or blueberries, and granulated sugar. Squeeze the juice of a lemon over the whole. Cover the top with slices of bread buttered on both sides. Place a plate over the dish, and bake for an hour and a half, setting the dish in a pan of hot water.
Take the pudding from the oven, spread over the top a meringue of white of egg beaten lightly with sugar in the proportion of a tablespoonful of sugar to one egg, and return it to the oven just long enough to lightly brown the meringue. The pudding should be eaten hot with hard wine sauce.
