Only recently I made some runner bean wine. It sounds awful, but I am told it actually tastes good.
I've also tried this with some of my runners this year,

it needs leaving three months, but smelled gorgeous when I sealed up the jars, so I have every hope for it.
Personally, I find runner beans pretty awful things and grow less and less each year. They are only nice when they are small and stringless, I've tried freezing them blanched, cooked and raw, but mostly they are awful and end up becoming compost. I mostly grow French climbing beans now. I can do all the things I would do with runners, but they can be used in stir fries, curries, salads, pickles and they freeze well. More importantly they defrost well. I have even dehydrated them and used them to good effect.
if the neighbours aren't already running away and shutting their doors at the sight of yet more free runner beans, give the damned things away as fast as you can!
