Jerusalem artichokes is also known as sun chokes. This Rich Guilty pleasure is an excellent side to a baked ham, roast pork, Turkey or chicken. The sauce is garlicy and creamy. I add fennel seed to help with expelling gas as sunchokes have the same reputation as the cabbage family. ;) Yes you can sub potatoes, parsnip, turnips, or carrots.
