You'll find my recipe for sunchoke soup on Gardenista. I loved my sunchoke aka Jerusalem artichoke (Helianthus tuberosus) plants; one of the most interesting crops I have grown. And, for the record, neither the Frenchman and I have been affected by the alleged (f)articoke syndrome. Cooking them in water fixes that. In case you are AFRAID!
Don't be. They are delicious. And in shops and markets now. Assuming you live in the Northern Hemisphere.
We have not actually had much appetite, lately. But soup is acceptable.
You can also drown yourself in it if it gets too much.
