The fruit with varieties named "Bing" and "Rainier" is the cherry. Bing cherries are known for their deep red color and sweet flavor, making them one of the most popular varieties in the United States. Rainier cherries, on the other hand, are recognized for their yellowish-red color and delicate sweetness. They are often considered a gourmet variety and are prized for their taste. Cherries are typically in season during the summer months and are enjoyed fresh, in desserts, and in preserves. Both types of cherries are especially popular in baking and cooking.
