Cut some mushrooms into pieces, press them in a cloth, and then mince them; do them up in a little melted butter, then add some good stock parsley, scallions," two cloves of garlic; skim and cook them over a moderate fire for half an hour, strain, take off the fat, and serve it very hot.
Have ready some cream sauce rather thinner than usual, to this put a few small white mushrooms, reduce it to the proper consistence, it is then ready.
Get a pottle of fresh mushrooms not opened, or coloured in the inside, cut off all the dirty ends, have two basins ready with a little water, salt, and the juice of two lemons; then pare or trim your mushrooms, putting the mushrooms in one water and the parings in the other; when all done put about two ounces of butter in a stewpan, take your mushrooms out of the water and put them into the other stewpan, cover them over, and let them stew for sometime; then put them by ready for use, then take out the parings after washing them well, and chop them very fine, then sweat them down in a little butter; when done put them in the larder until wanted. This comes in for Italian sauces, and various other things.
Put two ladlefuls of brown consomme, commonly called espagnole, into a stewpan with two ladlefuls of sauce tournee, and some mushrooms; reduce it over the fire to the thickness of the sauce you put in at first, then stir in a piece of butter, the juice of half a lemon, and a very small quantity of cayenne pepper.
Put two glasses of stock, shalots shred small, salt and pepper, into a saucepan, let them boil for half an hour, then add a tea-spoonful of mustard, stir it in well, and use it when required.
