The trick to getting the jello out of the pan: If you have trouble getting the jello out of the pan, immerse the pan in warm water (not hot). Use enough water to go up the sides of the pan, being careful not to get water in the jello. Leave the pan in the water for no more than 30 seconds. Remove the pan from the water. Slice the jello into squares with a sharp knife and use a small metal spatula to remove the jello.
