Boil one pint of water in a saucepan ; put in another vessel four ounces of powdered sugar, mix in one ounce of corn-starch, grate in the rind of a sound lemon, squeezing in the juice, and mingle well together with the spatula for one minute. Break in two whole eggs, beat all together for one minute, and add it to the boiling water in the pan, stirring sharply with a wire whip until it comes to a boil ; then take from off the fire. Have ready a lined, flat pie-plate as for mince pie (No. 1082), put it in the oven, and let it bake for ten minutes, so that the crust gets a good golden color. Remove from the oven, and pour the preparation into it, then let it get thoroughly cold. Beat in a copper basin three egg whites to a stiff froth, using a wire pastry-whip; mix in three ounces of powdered sugar, and with a spoon lay half of it over the pie, using a knife to flatten it evenly on the top and sides. Slide down a fancy tube (No. 3) into a pastry-bag (No. 1079), and pour the rest of the froth into it, then decorate the top of the pie artistically, laying it in any fanciful design. Sprinkle plenty of sugar over, place it in a slow oven for ten minutes to let get a pale brown color, then remove it, put it away to cool, slide it carefully onto a dessert-dish, and send to the table.
