Abundant Jerusalem Artichokes

The edible part of a Jerusalem artichoke is the tuber, which is the food storage portion of the plant, allowing it to winter over with nice nutrient reserves for the spring. Tubers can vary in size and shape, from round to knobby to long and slim. They also vary in color, sometimes depending on the variety, and sometimes they just vary. Colors range from beige to reddish to purplish on the outside, but all are creamy-white inside, as far as I know. The color doesn’t affect the taste.
