Jerusalem artichoke is called “foreign ginger” for its shape like ginger, but it is actually a kind of wild vegetables and is not spicy. When putting Jerusalem artichoke into a jar with homemade chopped peppers for fermentation, you will get a very appetizing snack, which is crispy, spicy, sweet and sour. It can regulate the sugar level in the blood- lowering it when it is high and raising it when it is low.
