Put six egg yolks in a copper basin, with two ounces of powdered sugar, half a gill of maraschino, and a quarter of a gill of Swiss kirsch. Then with a pastry-whip beat well together for two minutes. Place the basin on a hot stove, and stir briskly with the whip for five minutes. Remove it from the fire, and immediately put the basin into a vessel containing ice-water, and stir continually for two minutes more. Add a pint and a half of whipped cream a la vanille (No. 1254), and mix well with the rest for three minutes. Then cover the basin with a napkin, and let repose for ten minutes. Have six paper cases, four inches long, two inches wide, and one and a half inches high, and fill equally with the above preparation. Have ready a square biscuit-glace box, ten inches high by six inches square, and having inside a loose, two-tier frame. Place this box in an ice-cream tub, filling it with broken ice mixed with rock-salt. Wipe the cover neatly, and after lifting it up, remove the frame and place three biscuits on each tier; return the frame to the box, put the cover on, and let freeze for one and a half hours. Have a cold dessert-dish covered with a folded napkin; uncover the box, lift up the frame, and dress the biscuits nicely on the dish, sending them to the table at once.
