20 greengages, 4 eggs, 3 tablespoonfuls of ground rice, 1/2 oz. of butter, 1/2 pint of milk, 1/2 a teacupful of water, sugar to taste. Skin and stone the fruit; blanch and drop (or grind) the kernels; gently cook the greengages in the water with the kernels and sugar. When the fruit has been reduced to a pulp mix in gradually the ground rice, which should have been smoothed previously with the milk; add the butter and let the whole mixture boil up; draw the Saucepan from the fire and stir in the yolks of the eggs and then the whites beaten to a stiff froth. Pour the mixture into a well-greased dish, and bake the Soufflé‚ for 1/2 an hour in a brisk oven. Serve immediately.
