Take six ounces of macaroons (No. 1210); put them into a tin pan, and place it in a moderate oven to dry for ten minutes. Remove, and lay them on a table to cool off for twenty minutes, then put them in a mortar, pound thoroughly, and sift them over a sheet of paper. Have ready a vanilla ice-cream as for No. 1271, and just before serving add to it the sifted macaroons, and with the spatula mix thoroughly for five minutes, and with this fill a three-pint brick-mold, covering it tightly. Have ready a pail with broken ice and rock-salt at the bottom, lay the mold over, and fill up the pail with more ice and salt. Let it freeze for two hours, and when ready to serve, have ready a vessel with warm water, take up the mold, bathe it in the water, and wash off all the salt and ice that adhere, then unmold the ice-cream onto a dessert-dish with a fancy paper over, and send to the table immediately.
