The cranberry is a small sour fruit. It is so sour that most people can't stand to eat fresh cranberries alone. Cranberries contain edible seeds and plenty of air. Cranberry juice has been shown to reduce bladder infections in a nursing home environment. Cranberries are popular as juice, dried fruit, and a jam or jelly called cranberry sauce - all with added sugar of course. One single grower's cooperative, Ocean Spray, controls 70% of the cranberry crop.
