Mushrooms Rise Far Above Their Dark, Damp Heritage
The cultivation of mushrooms, known since the 17th century in France, boomed during the Napoleonic era, and mushroom farms sprang up in abandoned quarry tunnels on the outskirts of Paris.
I once had friends who lived in a converted mushroom “farm” right in the center of Paris. The loft-like space was unbearably dark and damp, better for the cultivation of mushrooms than friendly conversation.
Mushrooms are saprophytes - that is, they must live off the remains of other organisms because they are unable to photosynthesize sugar into energy. That accounts for why mushrooms are found in dark places; they need little light. They often grow at the base of trees, from whose roots they extract the necessary sugars. But, there’s no free lunch, as they say, and mushrooms give trees soil minerals in return for their sugars.
Other than the common cultivated white mushroom, certain highly prized wild species have always been popular visitors to the dinner table during the damp spring and autumn months.
Ribbed, pale-orange chanterelles and honeycomb-capped morels come to mind. Common in Europe, but more difficult to find here (except dried), is the famous Boletus edulis - called porcini in Italy, cepes in France.
Two Asian mushroom varieties have become common in recent years: the meaty, dark shiitake and the astringent, pale oyster mushroom.
Traditional cooking has used mushrooms more as a condiment than as a food. This is a happy coincidence, as mushrooms are not known to be nutritional powerhouses. They are very rich, though, in glutamic acid, which makes them a natural source of MSG. They add their own intense flavor to soups and sauces, and can save bland vegetable dishes.
Mushrooms change composition after harvesting; storing them refrigerated and tightly wrapped only hastens spoilage. Knowing this, be sure to buy small amounts at a time and use them quickly.
Purchase only the whitest cultivated mushrooms. When choosing chanterelles, look for ones with a solid texture, neither mushy nor wet. Shiitake should have plump caps with off-white undersides; remove the stringy stems and use them to flavor stocks and broths. Oyster mushrooms should be white with unbroken caps. Trim the stems, which are bitter except on the very small mushrooms.

Warm Mushroom Loaf With Tarragon Sauce
3 pounds assorted mushrooms, washed
3 medium onions, finely minced, about 2-1/4 cups

Pour mixture into greased 2-quart loaf pan or bundt mold. Cover, place in water bath with boiling water and bake at 375 degrees for 2 hours. Loaf is cooked when toothpick inserted into center comes out clean. Remove loaf from oven, remove from water bath and set aside.
Meanwhile, pour wine in saucepan. If using dried tarragon, add it now. Place over medium heat and cook until liquid reduces by half. If using fresh tarragon leaves, add them now. Remove from heat, whisk in butter, set aside and keep warm.
Unmold mushroom loaf and slice into 1-1/2-inch slices. Arrange slices on plates, spoon some tarragon sauce over corner of each slice and serve.

Wipe mushrooms, if necessary, to remove any sand or dirt. Slice chanterelles and cultivated mushrooms, trim and discard stems of shiitake mushrooms, trim and discard root tips of oyster mushrooms.
Bring 4 quarts cold, salted water to boil over high heat on stove.
Melt butter in large skillet over medium heat and add mushrooms, garlic, shallots and salt. Cook, stirring, 15 minutes.
