Jerusalem Artichokes are the perfect crop for the lazy gardener. You buy a few from your local greengrocer, plant them somewhere discreet in the garden, then come Autumn you have a wonderful crop. Leave a few tiddlers in the ground, and you'll have an even better crop the following year; and so on ad infinitum. They do not fail.
This year I have established a small dedicated plot up at Haddock's. In Spring, I planted about 6 tubers; but those I'll leave till later. These, above, grow at the base of a wall surrounding the pool, and are semi wild.
Last week I did notice some on sale at my supermarket, but they were all long and thin; rather like my little finger. Much too small, and difficult to clean. Mine above are far superior, and clean quite easily with a small nail brush.
I'm roasting a Chicken tonight, so they will roast amongst a few potatoes. Totally delicious; even if they do make you fart.
