I have not thought it necessary to repeat long descriptions of how the various species may, or may not, be cooked; it has been done to a great extent before. It is apparent that the addition of “good beef gravy,” “a few slices of fowl,” “rich veal stuffing,” and various other savoury condiments, must occasionally give an extra zest to a dish of mushrooms; but broiled, stewed, or pickled, most species are “always good alike”; indeed, mushrooms, in their whole composition, resemble meat in so remarkable a manner, that any methods of cookery in vogue for delicate preparations of meat, apply with equal force to mushrooms. Mrs. Hussey and Mr. Cooke each give a large number of _récipés_ for preparing these vegetables for the table; and to any reader who may wish to go deeper into the culinary branch of fungology, I must refer them to these authors. I must confess that I consider no preparation of mushrooms can exceed the delicious, inviting, and grateful flavour possessed by mushrooms when simply fried with butter, salt, and pepper. The various species suitable for storing up for future use—such as the Morel, Champignon, &c.—may be readily dried in a current of air, in a sunny window, or in a cool oven, and then kept in tins, or threaded on strings and kept in a very dry place. Occasionally this process goes a step further, and the mushrooms (of any species) are dried to such an extent as to be readily pulverized; the dust is then known and sold as “mushroom powder.” Housewives will now and then pickle mushrooms, by throwing them into scalding vinegar, allowing them to boil for ten minutes or so, and then, by adding cayenne, mace, nutmeg, or spices, adapt them to their various tastes. The liquor extracted from the various edible mushrooms, under the name of “ketchup,” is used in every kitchen, and the mode of preparation is probably known to all. It simply consists of placing the freshly-gathered plants in earthen jars with layers of salt; after a few hours the ketchup exudes in abundance from the fungi; and the process is ultimately completed by mashing the remains of the mushrooms with the hands. It should then be strained and boiled with spice and pepper, or strained and bottled, and the corked and scaled bottles placed for several hours in boiling water. The ketchup should then be kept in a cool and very dry place. Nearly every species figured on the Edible Sheet will produce ketchup of good quality, if treated with salt in an earthen jar. The Champignon and Horse Mushroom may be specially referred to as producing this condiment of an excellent quality. The juice exuded from the truffle in boiling is highly relished by many, as is the deep blood-red juice that runs from the “liver fungus” when cut. This, when seasoned with salt and pepper, and boiled, has a very delicious and stimulating flavour.
