This is delicious and the kids loved it too!  A good spin on the classic strawberries and rhubarb. Will be making this again!

This dish was very well received when I made it for an event.  I was worried that kids would find it too tart, but that was not the case.  I did use apple juice in place of the cranberry juice with no problems.

This was SO good, but the version we made in a Cooking Matters class was adjusted quite a bit. Instead of the cranberry juice/sugar/cornstarch mixture, we did a mix that was the juice of an orange, then added enough applesauce to make a full cup when combined with the orange juice, and 1.5 tablespoons cornstarch instead of 2. We also added some cardamom to the filling, and cinnamon/desicated coconut/cinnamon to the topping. It was seriously delicious!

I made this a couple nights ago with this spring's fresh rhubarb and last summer's frozen blueberries! I used orange juice and found the amount of cornstarch to be just right for a sauce on the fruit. I love that this dessert is not too sweet and the amount of topping is not too much. In fact, it made a delicious breakfast the next day with plain yogurt.
