58. YEAST
Take a good single handful of hops, and boil for 20 minutes in 3 pints of water, then strain, and stir in a teacupful of flour, a tablespoonful of sugar, and a teaspoonful of salt; when a little cool put in 1 gill of brewer's yeast, and after four or five hours cover up, and stand in a cool place for use; make again from this unless you let it get sour.
