My jerusalem anrtichokes are ready for harvesting. I’ve been advised, however, that they don’t keep well once dug up. My plan therefore is to only harvest as required for the time being although they can’t stay in the ground for too long as they’ll probably rot during our wet winter.
I would, however, like to be able to enjoy homegrown Jerusalem artichokes later in the year and not have to eat them all in the next two months. So I am going to experiment with fermenting/preserving some. My plan is for a very short ferment before refrigeration to help retain the crunch and not to alter the flavour too much.
Jerusalem artichokes (sunchokes) are exceptionally rich in Inulin, a type of soluble fibre than humans can’t digest well. It therefore reaches the colon intact where it acts as a prebiotic fuel source for beneficial microbes like Bifidobacteria and Lactobacilli. Inulin is beneficial as it promotes bowel regularity, helps calm inflammation and can improve the health of the gut lining. Because Inulin is fermented slowly in the gut it has a low glycemic impact and won’t cause blood sugar spikes.
However, the high Inulin content can cause significant gas, bloating and discomfort in some people. Fermenting the artichokes can make them easier to digest so sounds like fermenting artichokes is the way to go as it will both preserve them and make them easier to digest.
Another idea for your excess Jerusalem artichokes is to make miso with them. I did this last year and found that they make an excellent miso.
