milk, a few grains of salt.
_Mode_.--Mix the butter and flour smoothly together on a plate, put it
into a lined saucepan, and pour in the milk. Keep stirring it _one way_
over a sharp fire; let it boil quickly for a minute or two, and it is
ready to serve. This is a very good foundation for onion, lobster, or
oyster sauce: using milk instead of water makes it look so much whiter
and more delicate.
_Time_.--Altogether, 10 minutes. _Average cost_ for this quantity, 3d.
