Put in a saucepan six ounces of fresh butter, six ounces of powdered sugar, six egg yolks, and the grated peel of a medium-sized, sound lemon, squeezing in the juice as well. Set the pan on the hot stove, and with a wire pastry-whip stir sharply for at least five minutes. Remove from the fire and lay it on a table; beat in a copper basin the six egg-whites to a stiff froth, and add them to the other preparation, beating with the whip thoroughly but not briskly for ten minutes. Butter and sugar well six pudding-molds as for No. 1134, fill them with the preparation, steam them in a tin pan, and serve exactly the same as for custard pudding (No. 1154).
