I don't know where I found the recipe for Cherry Gelatin Fruit Salad, but I've been making it for over a decade. It is my most requested congealed salad recipe. People are surprised when they find out it only uses four ingredients. You can't tell when you're eating it that those four ingredients are sugar-free.
I love to use decorative molds when I make congealed salads. If you don't have a mold, you can use any food container that has a distinctive shape. I've used silicone pans, cake pans and muffin pans. It's nice to make the congealed salad in holiday themed pans, if you have them. It adds festivity to the holiday table.
