To Unmold Jello Salad
Place the mold in a sink or large container willed with warm water, just to below the depth of your mold. Be careful not to let the water go into the mold. Hold it there for 5-15 seconds, depending on the temperature of your water.
Tap all along the sides of the mold with the heel of your hand to loosen jello. If necessary, you can run a knife along the edge of the mold to loosen.
Place a platter, larger than the diameter of the mold on top of mold. Flip the mold and plate upside down, simultaneously. Jello should pop out.
If required, you can put the mold back in the water for a few seconds at a time. DO NOT leave the jello in the water for too long, or it will melt.
