Using up the artichokes

I can see why people only dig up Jerusalem artichokes when they need them. They don't store too well. I dug mine up a couple of months ago but many have gone mouldy or have dried out. So I am using up what's left. Tonight I made artichoke and onion soup. The rest I will make into artichoke gratin. For this latter recipe I hope to use an old wartime recipe for mock fish pie. I hope to film this one so watch this space.
