Jerusalem Artichoke and Groundnut (Hopniss)


I made Sunchoke vinegar pickles in the past Need Pickled Sunchoke/Jerusalem Artichoke Recipe They came out quite well. The carbohydrates in sunchoke are stored as inulin that breaks down to fructose after cold cycles. This is going to turbo charge any lacto pickle.

I need to get ready to pickle my stash I have a trash can full of them out back


I agree vinegar pickles would be the way to go once they sweeten up. I did my ferment while mine were still mostly inulin. Theoretically, the microbes break down the inulin for you.


There’s a thread on Permies where they recommend a bunch of different methods for cooking and preparation. The winning methods for dealing with the inulin so far: fermentation or freezing. Apparently freezing them for at least a week turns the inulin to sugar. Folks in colder regions liken them to candy out of the ground after winter, so chucking them in the freezer makes sense in that regard.

I sent out for three varieties from OIKOS. Supernova for sweetness, Red Fuseau for a standard red variety, and Spindel for strong (yet not bitter) flavor. I’ll report how they do in my tropical heavy clay once they arrive and I’ve grown them for a season.


Jerusalem artichokes and groundnuts are exceptional vegetables in my opinion, groundnuts may be my favorite vegetable. They taste like a cross of peanuts and potato and are very good roasted. I also really like jerusalem artichokes roasted and in stir fries as well as raw.


Was already planning to try Jerusalem artichokes. You folks have given me more to think about. Thanks!


i only realized jerusalem artichoke was edible about 5 yrs. ago. they grow all over old farmland here. i just thought they were a perennial sunflower. i imagine the old-timers must have eaten them as well. i dug some from a patch on a old road near here last summer. ones i got were huge and white. i found them pretty good but the wife didnt care for it. i wonder if the named cultivar ones are even better? i planted red and whites last fall.


When you harvest makes a difference as does how you prepare them. Spring harvesting will be sweeter fall will be more vegitable. You can boil them I also make deep fried chips that taste like or couse artichokes.

@robjohn Dont worry they are not as hard to control as people complain about. Just keep them mowed and they will exhaust there energy. But try them in a large grow bag or old trash can they grow great, easy to harvest and wont be able to spread.


Great idea about the container. This year I will cut a plastic 55 gal. drum in half and try some in that. At least it will be a start.


The top left is the result of a 5gallon grow bag. In my limited expreance sunchoaks seem to try to run there roots as far as possible and form tubers once they hit resistance. So the 55gallon approach might be counter productive. And overly heavy.


was that 1 seasons growth and how many roots did you start with?


Yes, one season and one per bag. I prefer the red cultivar I had. more knoblely less long. No difference in taste I could detect.

I just opened the way back machine and I bought them initially from . I then realized I had a vacant lot full of them but thats another story.


Once they grow, I expect to find they are all around us here. :smiley:


that and other natives


Sunchokes arrived.


Now the question. How do you keep them fresh till spring. Well you can keep them in the bottom tray of the fridge. or you can get a 5gallon bucket and fill it with soil and put them outside.

These are the type of grow bags I use.


Did not realize how important the storage is. They started going soft, so I buried them in a pot outside till I have their final pot ready. Not sure they will make it.


Hmm. Apparently Jerusalem Artichokes are mildly allelopathic. Methinks I’ll plant them separately…


oh they will. you can freeze them rock hard and they will survive.


You are right. I transplanted them last week into their new barrels. They were hard and had new nubs on them. Looking forward to future. :slight_smile:


On the other hand I read the abstracts of two studies one of which talked about how Jerusalem boosts microbial life in the soil that typically decrease in soil even with crop rotation. Inulin in the roots of all sunflowers and of course hugely abundant in suncoaks are bacterial candy.
