Take some fresh-gathered mushrooms; remove the stalks, and rub the flaps or heads very slightly with a little salt, mixed with cayenne. Then stew the mushrooms in a small sauce-pan, with barely sufficient cream or rich milk to cover them. Put in with them a small onion; and if the onion is found to turn blackish, throw away the whole; it being proof that there is among them a false or poisonous mushroom. Stir them with a silver spoon, and keep on the lid of the pan closely; unless when you are stirring. If the spoon turns black, the mushrooms should not be eaten.

After they have come to a boil, take them off the fire; drain them, and when cool, chop them small. To a pint or more of the minced mushrooms, allow six or seven eggs. Beat the eggs till very light and thick, (omitting the whites of two,) and then mix in, gradually, the mushrooms; stirring the whole very hard. Put three ounces of fresh butter into a hot omelet-pan, or a small frying-pan; place it over the fire, and stir the butter as it melts. When it has boiled hard, put in the omelet mixture, and as it fries, stir it till it begins to set. Do not turn the omelet; but brown the top by holding close above it a red-hot shovel. When done, drain off the butter; fold over or double the omelet; and serve it up immediately, on a hot dish.

In gathering mushrooms, those that are fit to eat may be known by their being of a pale pearl colour, or of a grayish white, instead of what is called a dead white; and the under side of the flap or head (if good) is of a light pink, or a pinkish salmon colour. The best mushrooms grow on uplands, or in high open fields where the air is pure and good, and they should be gathered early in the morning before the dew is off. All that are found in low swampy ground, or in the woods, or under large trees are poisonous.
