Are runner beans the same as string beans?
Keeping this in consideration, what are the beans inside green beans called?
Green beans are often called “string beans” for the long fibrous stem that runs along the outside of the bean, or “snap beans” due to the loud SNAP! they make when they are opened. They are actually immature kidney beans harvested young before their pods become too fibrous to eat.
Likewise, can you just eat the beans from runner beans?
For if you open a scarlet-flowering mature runner bean, one too fat and long for eating, you will find the prettiest beans inside. You can eat them fresh or dried (but never raw as they contain toxins which are broken down only by cooking). It's a peculiarly British thing to eat the pods.
From what I am aware of, green beans and string beans are one and the same. Some call them snap beans too. They are all the same thing. The only difference is the type of the green bean plant that comes in two varieties- bush and climber.
