Rub the rind of two small lemons on a lump of sugar ; crush it very fine with a roller, mixing three ounces of powdered sugar with it. Put two ounces of this into a saucepan with two ounces of sifted flour, one egg yolk, and two whole eggs, two teaspoonfuls of good brandy, and half a saltspoonful of salt. Stir all together with a wooden spatula, and after two minutes, when the paste is well mixed, stir it again for one minute only. Put two ounces of good butter into a separate saucepan ; as soon as the scum rises, stir it carefully for one minute, and let it cool slightly. Then spread it well over the sides of a three-pint made-leine-mold. Put the saucepan containing the preparation on a very slow fire ; stir slightly to prevent it adhering to the bottom of the saucepan, and as soon as it becomes liquid take it off, and fill the mold. Lay it in a moderately heated oven for forty-five minutes ; remove, and let cool. Unmold it on a dessert-dish over a folded napkin, and serve.
