Where the mold is to be only coated with jelly, first paste a piece of paper over the top of the mold; when it is firm, cut an opening in the paper, and pour in some cold, but liquid, jelly; and turn the mold on ice slowly, so that every part may be coated. Pour off any of the jelly that has not adhered to the sides; remove the paper, and lay in the material which is to fill the center of the mold. This method is employed where only a thin coating of jelly is required. Where it is to be an inch or more in thickness it is better to use a double mold.
When molding jelly have a pan of cracked ice, and set the mold into it. The jelly will then quickly harden. The mold must be perfectly firm and upright, or the jelly will not stand straight when unmolded. Do not oil or grease a mold used for jelly.
