In Europe several species of mushrooms are preserved by boiling and afterwards placing them in earthern jars or tubs filled with water, which is renewed from time to time. This simple and economical method of keeping mushrooms affords the people considerable provision. With regard to the preparation of fresh mushrooms for table use, Dr. Roques, an eminent writer on fungi, gives the following excellent suggestions: "After selecting good mushrooms, remove the skin or epidermis, cutting away the gills, and in some cases the stem, which is usually of not so fine a texture.
"It is important to collect for use only young and well-preserved specimens, because a mushroom of excellent quality may, nevertheless, when overmature or near its decline, become dangerous for food. It then acts as does every other food substance which incipient decomposition has rendered acrid, irritating and indigestible. It is, moreover, rarely the case that mushrooms in their decline are not changed by the presence of larvae."
In Geneva a very lucrative trade is carried on in the exportation of the "Edible Boletus," which is preserved for use in various ways, the simplest of which consists in cutting the caps in slices and stringing them, after which they are placed on hurdles in the shade to dry. They may also be dried in a stove or oven, but the former method is preferable, as the mushroom then retains more of its flavor or perfume. When the slices are perfectly dried they are put into sacks and suspended in a dry, airy place. Sometimes before the mushrooms are sliced they are plunged into boiling water for an instant, which treatment is said to preserve them from the ravages of insects. Several kinds of mushrooms are preserved in the following manner: After they have been properly washed and cleansed, they are boiled in salted water and afterwards wiped dry. They are then placed in layers, in jars, sprinkled with salt and pepper, and covered with pure olive oil or vinegar. Lactarius deliciosus, Cantharellus cibarius, Morchellas, Clavarias, etc., are thus preserved. Before using the dried mushrooms they are soaked in tepid water for some time and afterwards prepared as if fresh, with the usual seasoning.
RECEIPTS.
Broiled procerus.--Remove the scales and stalks from the agarics, and broil lightly on both sides over a clear fire for a few minutes; arrange them on a dish over freshly made, well-buttered toast; sprinkle with pepper and salt and put a small piece of butter on each; set before a brisk fire to melt the butter, and serve quickly. Bacon toasted over mushrooms improves the flavor and saves the butter.
Agarics delicately stewed.--Remove the stalks and scales from the young half-grown agarics, and throw each one as you do so into a basin of fresh water slightly acidulated with the juice of a lemon or a little good vinegar. When all are prepared, remove them from the water and put them in a stewpan with a very small piece of fresh butter. Sprinkle with pepper and salt and add a little lemon juice; cover up closely and stew for half an hour; then add a spoonful of flour with sufficient cream or cream and milk, till the whole has the thickness of cream. Season to taste, and stew again until the agarics are perfectly tender. Remove all the butter from the surface and serve in a hot dish garnished with slices of lemon. A little mace or nutmeg or catsup may be added, but some think that spice spoils the flavor.
Cottager's procerus pie.--Cut fresh agarics in small pieces; pepper, salt, and place them on small shreds of bacon, in the bottom of a pie dish; then put in a layer of mashed potatoes, and so fill the dish, layer by layer, with a cover of mashed potatoes for the crust. Bake well for half an hour and brown before a quick fire.
A la provencale.--Steep for two hours in some salt, pepper, and a little garlic; then toss them into a small stewpan over a brisk fire with parsley chopped and a little lemon juice.
Agaric catsup.--Place the agarics of as large a size as you can procure, layer by layer, in a deep pan, sprinkling each layer as it is put in with a little salt. Then next day stir them several times well so as to mash and extract their juice. On the third day strain off the liquor, measure and boil for ten minutes, and then to every pint of liquor add half an ounce of black pepper, a quarter of an ounce of bruised ginger root, a blade of mace, a clove or two, and a teaspoonful of mustard seed. Boil again for half an hour; put in two or three bay leaves and set aside until quite cold. Pass through a strainer and bottle; cork well and dip salt on the gills. Lay them top downwards on a gridiron over a moderate fire for five or six minutes at the most.
To stew mushrooms.--Trim and rub clean half a pint of large button mushrooms. Put into a stewpan 2 ounces of butter; shake it over a fire until thoroughly melted; put in the mushrooms, a teaspoonful of salt, half as much pepper, and a blade of mace pounded; stew until the mushrooms are tender, then serve on a hot dish. This is usually a breakfast dish.
Mushrooms a la creme.--Trim and rub half a pint of button mushrooms; dissolve in a stewpan 2 ounces of butter rolled in flour; put in the mushrooms, a bunch of parsley, a teaspoonful of salt, half a teaspoonful each of white pepper and of powdered sugar; shake the pan for ten minutes; then beat up the yolks of two eggs with two tablespoonfuls of cream, and add by degrees to the mushrooms; in two or three minutes you can serve them in sauce.
Mushrooms on toast.--Put a pint of mushrooms into a stewpan with two ounces of butter rolled in flour; add a teaspoonful of salt, half a teaspoonful of white pepper, a blade of powdered mace, and a half a teaspoonful of grated lemon; stew until the butter is all absorbed; then serve on toast as soon as the mushrooms are tender.
