Cranberries are tart, deep-red berries that grow on low evergreen shrubs in acidic bogs and are widely cultivated across the northern United States, Canada, and Chile. They are consumed fresh, dried, juiced, or sweetened and are particularly associated with North American holiday cuisine.
History & Origins
Indigenous peoples of the northeastern woodlands, including the Wampanoag, Lenape, and Ojibwe, harvested wild cranberries long before European contact, using them in pemmican, sauces, and as a pigment and wound poultice. English and Dutch colonists adopted the fruit in the early 17th century, and commercial cultivation began in Massachusetts in the 1810s, eventually making the cranberry one of the few fruits native to North America that became a major commercial crop.
