Béchamel sauce for meat
A roux of butter and flour should be thinned with a cupful of veal or chicken stock, seasoned with onion juice, a small carrot, sliced, pepper and salt. Strain the stock before mixing with the roux. Have ready a cupful of rich milk or cream, heated with a pinch of soda; draw the hot stock and roux from the fire, stir in the cream, and it is ready for use.
Béchamel sauce for fish
Put the bones, head and a few ounces of fish meat in cold water over the fire, with an onion and a small carrot, sliced, also a bay leaf; boil down to one cupful of liquid, and use instead of veal or chicken stock in last recipe. In all other respects make in the same way.
Oyster sauce
To a white roux of butter and flour add a cupful of boiling liquid made by cooking a dozen oysters in hot water for two minutes. Drain the oysters (which should be very small) and keep warm while you stir the thinned roux to a smooth cream, and season it with a dash of cayenne, a teaspoonful of lemon juice and a little salt. Boil one minute, put in the oysters and take at once from the fire.
Lobster sauce

Horseradish sauce
Into a cupful of drawn butter beat a great spoonful of grated horseradish wet with lemon juice, and work to creamy whiteness.
