Home-made Yeast. No. 1. (Beechwood.)
1 oz. hops boiled 3 hrs. in 1 gall. of water. Strain, and pour it over 1 qt. of malt. Let all stand 4 or 5 hrs. covered up close. Strain again, and add ½ lb. of flour, and 2 tablespoonfuls of common yeast.
Put this all together into a stone jar, and it will be ready for use in 2 days.
Half as much again is generally necessary of home-made yeast to raise bread than of brewer's yeast.
Another recipe says: In choosing hops to make home-made yeast, get old, yellow-looking ones; for the fresh, which are green, are incurably bitter.
