(Coming as soon as I can grow mine this year)Harvesting Info:
Dig tubers in August or late fall after the plant has died down. The tubers must be kept moist after harvesting. They can be stored wrapped in a damp paper towel in a plastic bag in the refrigerator, or stored in a root cellar, or left in the garden until needed.Cooking Info
Jerusalem artichokes can be eaten raw or cooked. When cooked, they taste a lot like a moist potato.Warning! When fresh, Jerusalem Artichokes contain the starch inulin. Eating inulin can cause gas and bloating in some people. Don't over-indulge! Also, apparently the inulin is converted to regular starch during storage, so you might want to wait a bit after harvest to cook them. The amount of time needs more research.
Boiled Jerusalem Artichokes: Wash and peel the tubers. Place them in a pot and cover with water. Boil about fifteen minutes until tender and drain. You can eat them as is, or add salt, butter and chopped parsley, or you can mash them with milk and butter as you would potatoes.
