A Nameko or Butterscotch is a variety of mushroom that grows in clumps of small mushrooms with a white stem with a bright orange cap and a mild flavour. When fresh, the caps have a shiny appearance and a slightly gelatinous feel which contributes to the unique flavour of this mushroom. Nameko is now being cultivated in Australia. This mushroom is an essential ingredient in Japanese cooking. It is commonly used in soups, stir-fry dishes or just cooked in a rice vinegar/soya sauce dressing.
