History

Shiitake (Lentinus edodes) is native to Asia with a rich history of use in the kitchen and in herbalism. In the 12th century, Shiitake Mushroom cultivation began in the mountains of central China. A fragrant and delicious edible mushroom, Shiitake is now the second most popular cultivated Mushroom in the world after the button mushroom.

Seasonality & Availability

While Shiitake are cultivated around the world, its natural habitat is hardwood forests throughout Asia. In nature, Shiitake spores are released from fruiting bodies in the fall or spring, traveling through the forest air and landing on both live tree branches and fallen limbs and logs. Healthy trees will overcome the Shiitake spores and live on, while the Shiitake spores will take over the dead branch and build a mycelial network that produces fruiting bodies.

Shiitake grow in groups on the decaying wood of deciduous trees, particularly chestnut, oak, maple, beech, sweetgum, poplar, hornbeam, ironwood, mulberry and chinquapin. Its natural distribution includes warm and moist climates in Southeast Asia.

Shiitake are now widely cultivated all over the world, and contribute about 25% of total yearly production of mushrooms. Commercially, shiitake mushrooms are typically grown in conditions similar to their natural environment on either artificial substrate or hardwood logs, such as oak.

The Chinese were the first to cultivate this mildly fragrant mushroom more than six hundred years ago. Yield and quality varied from year to year until scientific techniques were developed. Japanese scientists developed a method of inserting pencil-shaped plugs of mycelial spawn grown from specially selected varieties of Lentinus edodes into holes bored in oak logs. Carefully watched over in the forest, the prepared logs carried out the work that supported the entire shiitake industry.

You can find shiitake mushrooms fresh, dried, or in various dietary supplements.

Shop with care when purchasing dried shiitakes, since there are many grades and prices. The caps may be thick and fleshy, or thin; large or small; cracked on top or smooth. The very thick, cracked-topped donko types are expensive, but worth the price. They are meaty and can stand up to any food.

Nutritional content

Shiitake mushrooms are considered to be medicinal mushrooms in some forms of traditional medicine. The fruiting bodies of this mushroom contain polysaccharides, specifically a type called beta-glucans, which have been studied to support immune health and overall wellness, as well as normal, healthy cell growth and turnover.

Shiitake Mushrooms Culinary usage

Cleaning

Because shiitakes grow on wood or other coarse cellulose materials, the fresh mushrooms are very clean. Brush the caps lightly. As a rule, the stems are tough so cut them off before cooking. The stems can be used to add flavor to stock.

Cooking

Shiitake mushrooms will enhance the flavor of most foods.

Reconstitute dried mushrooms by soaking in hot or boiling water for 20 minutes. Save the liquid to include in another dish. Pour off the liquid at the top to separate it from any debris at the bottom of the dish in which it was soaked.

Mushrooms have a distinct umami flavor, which can be especially helpful when making vegan dishes. To select the best specimens, look for ones sold whole rather than sliced. The caps should be thick with deep, white gills.

When cooking with fresh shiitake mushrooms, remove the stems, which remain tough even after cooking. Save the stems in the freezer for making veggie stock. You can cook shiitake as you would any other mushroom.

My favourite way to cook shiitake is in with a little olive oil, garlic and thyme, pan-fry until golden brown, season with a little salt and small splash of soy sauce or red wine to de-glaze the pan.
