The difference between long beans and carob beans is the part of the plant they refer to. Long beans generally refer to the pods of leguminous plants, also known as green beans or peas. Carob refers to the state in which the pods of leguminous plants become elongated and contain beans after maturity. They are also called beans or pods.

This difference is mainly due to the growth and development process of plants. As the pods of leguminous plants grow, they gradually lengthen over time and the seeds inside mature. So, when the pods grow to a certain extent and contain mature seeds, they are called carob beans.

In addition, long beans and long beans can also be expanded in terms of eating methods and cooking characteristics. Long beans can generally be eaten as whole pods. They are tender and juicy and suitable for various cooking methods such as boiling, stir-frying, and stewing. For long beans, it is generally necessary to remove the seeds and only eat the pod part, which has a slightly hard texture and is suitable for cooking methods such as stir-frying, boiling, and stewing. It is also often used to make dishes such as stir-fried beans and meat.

In short, the difference between long beans and carob beans lies in the maturity and shape of the pods, as well as the way of eating and cooking characteristics.
