I love broad beans and grow a lot. My top tip which I am giving you free is that if you have a glut, pod them and put the beans in a tub and straight in to the freezer. If your freezer has a 'superfreeze' setting, use it.
No need for blanching or any of that nonsense - straight in to the freezer. When you want to cook them, put them in a saucepan with a bit of salt, cover in boiling water and boil them until tender.
I have been freezing them this way for many years and they keep perfectly well until the next harvest is ready.
