Storage and Handling

History

Despite its name, the Jerusalem artichoke has no relation to Jerusalem. It is not a type of artichoke but a tuber, the root of a type of sunflower. Originally it is from North America, where it is usually called a sunchoke. 

 

Facts

  • The Jerusalem artichoke is a bumpy, fleshy root vegetable
  • It is best cooked and can be used in the same way as potatoes
  • Unlike most starchy vegetables, the main storage carbohydrate is inulin rather than starch, which is tolerated by diabetics
  • Jerusalem artichokes discolour quickly so after cutting immerse them in water with lemon juice until cooking

 

Growing Facts

  • They grow from tubers which should be planted late winter or early spring
  • Jerusalem artichokes grow well in temperate climates in New Zealand 
  • Jerusalem artichokes are drought resistant
  • When fully grown Jerusalem artichokes have a yellow sunflower-like bloom on plants over 1.8 metres high
