Butterscotch

Wet a pound of brown sugar with a cupful of water, into which two tablespoonfuls of vinegar have been stirred. Put into an agate saucepan. Cook for ten minutes, add four tablespoonfuls of butter and boil until a drop hardens in cold water. Pour into large buttered tins, and as it cools, mark off into squares.
