The yard-long bean, also known as the Chinese long bean, asparagus bean, or snake bean, is a vigorous climbing annual vine that produces long, slender pods. These beans are actually legumes, belonging to the family Fabaceae, and are closely related to black-eyed peas and cowpeas. Yard-long beans can grow up to 14-30 inches (35-76 cm or 1-2.5 feet) in length, but are typically harvested at around 12-18 inches (30-45 cm) when they are still tender and before the seeds mature. They have a slightly sweet flavor and a crisp texture, which is retained even after cooking.
Common uses
Yard-long beans are often used in a variety of dishes including stir-fries, curries, salads, and as side dishes. They can also be pickled or used in soups. The beans are typically cut into smaller lengths for cooking and can be eaten both raw and cooked.
