Please help! Need to know for a friend who can only eat Jell-O in preparation for a medical procedure!
2 packages of jello will yield about 24 2" jigglers. So the number of boxes will depend on how much your friend will eat.
It's 2 packages Jello to 2.5 cups boiling water. No cold water added. Stir until dissolved. Pour into 13x9 inch pan and refrigerate for at least 3 hours.
