I have raised beds, and I noticed sunchokes beginning to grow this spring. I cut down (and thought I had ripped out) the single sunchoke I planted last spring sometime around Christmas last year thinking that was the end of it (didn't even try it after my friends told me horror stories about "severe gastrointestinal distress" they had experienced). I went to dig them up and ended up harvesting over 3lbs of sunchoke tubers (yeah, I weighed them, 3lbs 4.3oz). I'm feeling more adventurous now, and am curious if anyone has experience eating them after such a late harvest (they were sprouting new plants and were about 6 inches tall above the soil, and some of the tubers were over a foot deep. I really dug these things up).
Are they worth cooking, or should I just toss them?
