Gourmands' Mushrooms
Directions
Melt in a pan a lump of butter the size of a tangerine orange and squeeze on it the juice of half a lemon. The way to get a great deal of juice from a lemon is to plunge it first of all for a few minutes, say five minutes, in boiling water. When the butter simmers, throw in a pound of picked small mushrooms, stir them constantly, do not let them get black. Then in three or four minutes they are well impregnated with butter, and the chief difficulty of the dish is over. Put the saucepan further on the fire, let it boil for a few minutes. Take out the mushrooms, drain them, sprinkle them with flour, moisten them with gravy, season with salt and pepper, put them back in the butter and stir in the yolk of an egg. Add also a little of the lemon juice that remains. While you are doing this you must get another person to cut and toast some bread and to butter it. Pour on to the bread the mushrooms and serve them very hot.
