2 teaspoonfuls flour.
1½ ounce butter.
1 teacupful hot water or milk.
A little salt.
Put the flour and salt in a bowl, and add a little at a time of the
water or milk, working it very smooth as you go on. Put into a tin cup
or saucepan, and set in a vessel of boiling water. As it warms, stir,
and when it has boiled a minute or more, add the butter by degrees,
stirring all the time until it is entirely melted and incorporated with
the flour and water. Boil one minute.
Mix with milk when you wish to use for puddings, with water for meats
and fish.
