To make meringue, preheat oven to 400ºF. With egg whites in a large bowl, begin blending with a hand mixer until foamy. Slowly add the cream of tartar, cornstarch, and sugar, mixing well. Continue beating until you get stiff peaks. Add cider vinegar and vanilla, blending only until mixed in.
Place meringue into a glass pie dish. With a large spoon, mound the meringue higher around the edge, leaving the middle lower and flat, so it looks like a crater. Place in oven and immediately turn the oven off. Do not open the door! Leave in oven for at least four hours. (It's okay to leave it in overnight. It will be fine as the baked meringue does not need to be refrigerated.)
Spoon whipped cream into baked meringue crater. Fill as high as you would like and place in the fridge. Before serving, top with fresh sliced strawberries, kiwi and bananas. You will need to refrigerate any leftovers.
