A bucket full of Jerusalem Artichokes. They're related to sunflowers. In fact, mine grew bigger than any sunflower - but the flower was only the size of a mouse!
This is my first ever harvest, and this bucket full came from just one plant! And there are still more to be dug out (though they apparently don't store well, so you keep them in the ground until they are needed).
Apparently they're very nice roasted, or mixed with parsnip and cheese/cream make a great bake. Anybody know of any good recipes?
