Introduction to Long Beans

Long beans, also known as yardlong beans, snake beans, or asparagus beans, are a versatile and nutritious vegetable native to the tropical and subtropical regions of Asia. Their origins can be traced back to the mountainous areas of Myanmar and Thailand, where they have been cultivated for centuries.

Long beans are characterized by their slender, cylindrical pods that can grow up to 1-2 feet in length. They have a vibrant green color, smooth texture, and a slightly sweet and crunchy taste.
