Jerusalem artichokes are neither from Jerusalem nor are they artichokes. So, what are they?
Jerusalem artichokes are neither from Jerusalem nor are they artichokes. These knobby-looking North American natives (Helianthus tuberosus) are a species of the sunflower genus. When cooked briefly until just tender, they have a creamy texture and taste like a cross between potatoes and artichokes. Our tasters preferred them cooked longer until they were softer, with the consistency of a baked sweet potato. The longer cooking time also made them sweeter, with a deeper artichoke-like flavor. We recommend peeling Jerusalem artichokes before cooking them to remove their fibrous skin. When shopping for them, look for those that are the least knobby. They will be the easiest to peel.
