I'd just shell them and cook with other smaller runner beans or cook with other veg or put in a casserole.It's too much bother to blanch anything to freeze and it doesn't taste the same
Thank you all so much for all of your comments. And, thanks for letting me know that they could make me ill if not cooked right, I had no idea !
One last thing if I may... what makes them go tough?
Some were quite long but not too plump inside, cooked for approx 30 mins. Some were fine to eat but others were unpleasant in the way that it was like chewing a sweet with a very thin wrapper left on. And the wrapper didn't break down when chewed. Hope this makes sense!
My vine is still flowering so if I know where I've gone wrong I hopefully won't mess up again!
My Goodness, 30 minutes is way, way too long for runner beans which are fit to eat. You have let them grow for too long. Pick them when they are up to about 160cm and don't need stringing if they are a stringy variety.
One of the joys of your own veg is that you can pick things like beans much earlier than the tough things you find in the shops. And home-grown vegetables, fresh picked, take much less time to cook than recommended.
Thanks Welshonion, than explains a lot. I've never been that keen on beans until this year when I thought I'd give growing them a go. Normally I'm a tomato, cucumber & salad person, with which I have had great success.
Real Seeds sell a Greek runner bean which is huge, the beans inside being twice the size of normal beans. They are left on the plant untill brown, then the beans podded and dried.
