Cranberries are firm, round dark red berries. They are extremely tart with small interior seeds. Cranberries are great when baked in muffins and breads. Their intense flavour adds zest to relishes and sauces. Myths abound regarding cranberries' growth habitat. They are not grown in water in fact, they can't even survive in water. Cranberries grow on low, trailing vines that grow in bogs. These bogs are dry during the growing season, and flooded only during harvesting, which also helps protect the vines against cold winter temperatures.
