They are related to both strawberries and blueberries. In the culinary world, one of the most important factors in determining whether a cranberry is ripe or not is its color. The flesh should be bright red with a slight translucence so that it appears moist and fresh. This means that bogs should be harvested before they are completely dark because once they are too dark, the cranberries will no longer be juicy and will taste slightly sour.
Cranberries are berries that have a high water content, which makes them soft, juicy and sweet. Ripe cranberries are usually dark in color and have a high sugar content. Cranberries can last up to three weeks when stored in the refrigerator.
