The agricultural bean or Rashti bean is a type of bean native to northern Iran (especially Gilan Province) and is popular in the local cuisine of the region due to its unique flavor and delicate texture. This bean, which is usually creamy brown in color and smaller than some other types of beans, is used in traditional northern dishes such as "Lubia Polo Ba Mahi" and "Baqlaqimeh" and gives the food an earthy and pleasant flavor. Rashti beans are a rich source of vegetable protein, fiber, iron, and B vitamins. As a nutritious and filling food, they not only help with digestive health and energy, but also have always been considered a part of the region's cultural and culinary heritage on local tables.
