Mousseron (Marasmius oreades), also known as Fairy ring mushrooms or Scotch Bonnett
Mousseron mushrooms, are delicious, small wild mushrooms more universally
used in France and Italy than in
England - although it is well known and frequently used both in a fresh and
a dry state in England. It's commonly
found growing in "fairy rings" marked by dying grass in the center, on
grassy lawns or in parks and cemeteries .
Numerous conjectures were once put forth as to the origin of these rings
when their fairy connection was no longer
believed in. They were attributed to the out breathing of a lively
subterranean vapour, to the burrowing of moles,
even to the effects of lightning. The rings formed by Marasmius oreades
increase in diameter with time as the
fungus seeks new food. A number of studies measuring distance and growth
rate have estimated that some rings of the
M. oreades are probably centuries old and hundreds of feet across. The
French call it faux mousseron, or
"mushroom scythe", no doubt due to its nuisance potential for lawn
destruction; eventually the grass inside the
ring recovers, but along the borders the damage continues. One of the
first mushrooms to appear in spring, the
Mousseron mushroom tastes just as good as it looks.
This delicious mushroom can actually be found in the U.S. year-round
except during the coldest months in the
appropriate areas of the Northwest. The fairy ring mushroom fruits
abundantly during the warm months in the
eastern United States, and all year in the west; they are most easily
attained in California in late spring and summer
after rain or periodic watering. European season is Spring and Autumn. When
it is available, it is usually under the
French word "mousseron", which is a partial name from the following
choices: mousseron d'automne, faux
mousseron, mousseron de Dieppe, petit mousseron, mousseron des prés, and so
on. Richly colored, creamy off-white to beige, light tan to golden brown,
Mousseron caps are little more than 1 inch in diameter, with lacy, widely
separated buff-colored deep gills and long, delicate stems that appear very
fragile in comparison to the cap size; in reality the seeming fraility is
misleading, they are actually tough but edible, though not tasty. While
young, its cap is raised, the centers conical or dome shaped, getting
bigger with age, and has relatively thick flesh in the center of the cap.
They throw off many white spores. Beware of similar looking species that
are toxic.
From a culinary point of view, this is a versatile mushroom. Mousseron
mushrooms have a fine, full-bodied almost
aniseed flavor with a soft and chewy, fleshy texture like Boletes. There's
an almost magical earthy scent that goes well with meat and fish dishes,
omelettes, stuffings, or mixed mushroom dishes. The aroma and distinctive
taste of the delicious Mousseron is reminiscent of Porcini mushrooms,
almost nutty, toasty, with a slightly bitter almond edge. Although it is
delightful fresh, this mushroom is often dried before use. The caps are
thin and will dry quickly - try stringing them on a thread to hang in a
warm place for later use and it will retain its flavour remarkably well
this way. Or, simply dry on a baking sheet in an oven warmed by a pilot
light, with the door left a bit ajar; by morning, the mushrooms will likely
be dry and crisp. Dried Mousserons do reconstitute to their original
texture, appearance and taste, quite nicely, and provide wonderful flavor;
this mushroom is a delicious addition to your favorite soups, ragouts, or
stews, and it confers a definite, somewhat sweet taste, a quality which
also enhances some cookies. Tasty and fragrant, it is excellent sautéed in
butter with onions or garlic for a wonderful addition to pasta, bean or
rice dishes. This is the mushroom traditionally added to the British Isles
beefsteak and kidney pies, and is very much sought after by the French.
It's relatively unknown to American buyers and is highly priced.
To prepare for use, a light dusting with a brush would be advised over
washing them as that will compromise their
flavor. Clean the tops quickly under water with your fingers if necessary.
Remove the fibrous stems with scissors
and discard. Though literally edible, the stems are too rough and bitter to
eat with any enjoyment. Luckily, insects seldom attack these mushrooms. The caps are quite firm and tolerate long
cooking. When shorter cooking times are
called for, simmer them beforehand for 15 minutes in water with butter and
lemon juice. It is not necessary to soak
them, prior to adding to soups or stews, due to its amazing ability to
rapidly take up water; just add when and where needed.
