Scattone is a unique Italian soup originating from Molise. It's made with a combination of water from cooking pasta, red wine, and a pinch of pepper or a chopped diavolillo chili pepper. The pasta variety that's cooked in the water for this soup should be sagne or taccozze, and the water is poured into a separate cup once the pasta is about half cooked.
