Yest.
Boil one ounce of hops in three quarts of water until reduced to about three pints. Pour it upon one pound of flour; make[340] it into a batter; strain it through a colander, and, when nearly cold, put to it one pint of home-brewed yest. Put it into a bottle, and keep it for use. It should stand twenty-four or thirty hours before it is used.
