Jars of JELLO Rainbows

Although these take hours to layer and set up, the actual time in the kitchen is minimal. And so worth it! Make them a day or two ahead for a party.

Equipment

  • small canning jars

Ingredients
  

  • 7½ cups boiling water, divided (boil as you need it 1-1/4 cup at a time)
  • 6 boxes (3-ounce box each), JELL-O gelatin any flavors, (From Bottom to Top) for Rainbow Jars pictured: Grape, Berry Blue, Melon Fusion, Pineapple, Orange, Cherry
  • 1 cup plus 3 Tablespoons sour cream or vanilla low-fat yogurt
  • whipped topping, optional

Instructions
 

  • STIR 1-1/4 cups boiling water into 1 package gelatin in small bowl at least 2 minutes until completely dissolved. Pour ⅛ to ¼ cup of the dissolved gelatin into each individual jar. Refrigerate about 15 minutes or until set but not firm (gelatin should stick to finger when touched). It works best to put the jars on a tray that will fit in your refrigerator so it's easy to put them in and take them out. 
  • Refrigerate remaining gelatin in bowl about 10 minutes or until slightly thickened (consistency of unbeaten egg whites). Gradually stir in 3 Tbsp. of the sour cream into the remaining gelatin. Spoon over gelatin in jars. Refrigerate about 20 minutes or until gelatin is set but not firm (gelatin should stick to finger when touched).
  • REPEAT process with each remaining gelatin flavor. Be sure to cool the next layer of dissolved gelatin to room temperature before pouring into jars! It works best if you dissolve your next flavor of gelatin in boiling water when you are waiting for the previous layer to cool in the refrigerator. That way, there isn't as much time in between the creamy sour cream layer and the new color/flavor layer. Refrigerate gelatin as directed to create a total of 12 rainbow layers.
  • REFRIGERATE 2 hours or until firm. Top with whipped cream and a fun umbrella before serving. (If this is for a kid's birthday party, you could put candles in the jars instead.) Store leftovers in refrigerator.
