I am a fan of Wikihow, and have to admit I have read (without remembering) the directions for "How to make a vase out of a plastic bottle," "How to make crop circles," and "How to make a zoetrope."
I had all of the ingredients: watermelon, almonds, yogurt (substituted for sour cream) and honey. Plus a doughnut cutter. You just sweeten the yogurt, add it to the top of a watermelon ring, plunk another ring on top and frost it with more yogurt and a sprinkle of nuts. Bingo: you have a
dessert, no a fruit salad.
