Ingredients for 8-10 servings

1/3 c. (+ 1/3 c. more) frozen cherry juice concentrate
1/3 c. (+ 1/3 c. more) frozen orange juice concentrate (pulp-free)
1/3 c. (+ 1/3 c. more) frozen grape juice concentrate
5 pkg. (5 TBS.) unflavored gelatin total (1 for each of the three flavors, plus 2 for pineapple/cream layer)
2 c. boiling water (1/2 c. for each of the 3 flavors, plus for the pineapple/cream)
2/3 c. (+ 1/4 c. more) frozen pineapple juice concentrate
3/4 c. cream
Grapes or berries for garnish, optional

Directions

For this recipe, let get to room temperature, in three separate ceramic bowls (large soup bowls work): > 1/3 c. frozen cherry juice concentrate > 1/3 c. frozen orange juice concentrate (pulp-free) > 1/3 c. frozen grape juice concentrate
Soften gelatin by sprinkling into each bowl: > 1 pkg. unflavored gelatin (for each of the three flavors)
After 5 min. or so, add to softened gelatin: > 1/2 c. boiling water
Stir until gelatin dissolves. Microwave for 30 seconds or so, if necessary, to dissolve the gelatin. Last, add to each bowl: > 1/3 c. more of same concentrate
Pour each flavor into its own small loaf pan (5"x3" works well). Let set up in refrigerator for several hours. When jell-o loafs are firm, make the pineapple jell-o.
Into larger ceramic bowl, measure and let get to room temperature: > 2/3 c. frozen pineapple juice concentrate
Soften gelatin by sprinkling into the bowl: > 2 pkg. gelatin
After 5 min. or so, add to softened gelatin: > 1/2 c. boiling water
Stir until gelatin dissolves, microwaving the mix a bit if it's not dissolving. Last, add: > 1/4 c. more of pineapple juice concentrate > 3/4 c. cream
Refrigerate the pineapple mixture just twenty minutes or so, to get to the consistency of thin yogurt. Cut the loaf pans of flavored jell-o into 1" cubes, gently folding into pineapple-cream mix, pouring into a ring-shaped mold. Let set up until completely firm, half a day or longer. (You can make it the day before.) Before serving, briefly set the mold into a sink of hot water, just to warm the outside of the pan, moving quickly to invert it upside-down onto a plate. Garnish with grapes or berries if desired. Cut and serve!
