Our Shiitake Mushrooms are edible mushrooms that grow outdoors on oak logs. Known as the 'elixir of life' since ancient times shiitake mushrooms are an immune booster and contain a rich amount of minerals, vitamins B1, B2, B6, and an abundance of ergosterol that is not included in many foods (ergosterol becomes vitamin D2 to support the growth of bones and teeth). Our shiitake mushrooms are of the highest quality and grown organically, without chemicals and added flavours. Our Shiitake Donko is one of the highest ranked, richest tasting shiitake. Donko is a type of shiitake that grows slowly in a cold season and is gathered when its top is 60%-80% opened, making the meat soft in texture as well as rich in flavour and aroma are generated during the long period of growth. Dried Donko can be prepared for cooking by soaking it in water for about 2 hours. When soaked, Donko's flavour, aroma, and the Eritadenin that helps lower blood pressure, vitamins, and other substances are released into the soaking water so its recommended you use the liquid in soup, steamed dishes or sauces.
