The tubers can be stored in the vegetable container for two to three days. Jerusalem artichoke will keep for about a week in a plastic bag to keep the flesh fresh and prevent it from drying out.
The Jerusalem artichoke tubers vary in shape and color depending on the variety. Jerusalem artichoke tubers are round or oval-elongated and slightly gnarled, others are spindle-shaped and pointed at the end. They are like potatoes in color, the skin is brown-grey to a light violet or red. The flesh is white or cream-colored. The Jerusalem artichoke is related to the sunflower and is only sparsely cultivated in Europe.
The taste is often compared to that of the artichoke.
