I learned this the hard way, and so did Leif, who accompanied me on a long jog after I had lunched on Jerusalem Artichokes.
Didn’t take long to confirm that this easiest vegetable to grow has one major drawback:
“There is a reason why these vegetables are known as fartichokes. The cause is something indigestible called inulin. In 1621 the writer John Goodyer wrote, ‘…in my judgement, which way soever they be drest and eaten they stir up and cause a filthie loathsome stinking winde with the bodie, thereby causing the belly to bee much pained and tormented…. more fit for swine, than men.’ The last bit is a bit harsh. Wind is a small price to pay for the enjoyment of Jerusalem artichokes.”
