Cranberries are a rare and expensive fruit, originating in the United States and grown in cool climates with acidic soil. Due to their long growth cycle and preference for swampy areas, they are expensive to pick and preserve, resulting in a high cost. The fruit is nutritious, containing high levels of antioxidants, vitamin C, fiber, and vitamin K. It is used in various food products and is particularly floats on water, making harvesting unique and challenging.
