Rancho Gordo - Royal Corona Beans A hand-harvested crop straight from Europe into your pantry. Giant, fat, white runner beans that are creamier and more luxurious than Greek and Spanish gigandes and a little denser than traditional Italian coronas. Royal Corona beans can replace any white bean, but be prepared to be astounded by how big they are when cooked. Fully cooked, they can be a little starchy but you can also keep cooking until they reach the creamy point.
