All that is needed is a 3 ounce package of Jello, two packages of unflavored gelatin, and 1/3 cup of water. You also need candy molds.
Put the water in a saucepan, sprinkle on the Jello and gelatin, and let sit for 5-10 minutes. Then heat until the mixture melts. I poured it into a glass measuring cup to make filling the molds easier. Let sit for 20 minutes (or 10 minutes in the refrigerator).
One recipe filled two candy molds. I did have to put mine in the refrigerator to help it set since the kitchen was so hot. They were fairly easy to remove from the molds. It did require some pulling, but this is no way damaged the designs. I tried some Christmas designs as a test for the upcoming holidays. I can definitely see myself making these more often for the children (and adults) in my life. My husband declared them yummy.
