How to Unmold Gelatin
Allow gelatin to set several hours or overnight until completely firm. Before unmolding, dip knife in warm water and run knife around edge of gelatin to loosen. Dip mold in warm water, just to rim, for 15 sec. Lift from water and gently pull gelatin from edge of mold with moistened fingers. Place moistened serving plate on top of mold. Invert mold and plate and shake to loosen gelatin. Gently remove mold.
How to Layer Gelatin
Pour first layer of prepared gelatin into serving dish or mold. Refrigerate until set, but not firm, before adding the next layer. The gelatin for each additional layer should be cooled and slightly thickened before pouring over each chilled layer.
