Here’s something I never considered doing. Making my own yeast. This recipe comes from The Ladies Indispensable Assistant, 1850.
To Make Good Yeast
|Yeast Cake Today|
Take as many hops as you can hold in your hand twice; put them into three pints of cold water; put them over the fire, and let them boil twenty minutes: then strain the water into an earthen or stone jar, and stir in while the water is scalding hot flour enough to make a stiff batter: let it stand till about milk-warm: then add a tea-cupful of old yeast to make it rise, and a tea-spoonful of salaeratus dissolved in the old yeast; stir it well and put the jar in a warm place to rise. Some add Indian meal enough (after it has rise well) to make it into cakes and dry it on a board in the sun. This is very convenient, especially in hot weather, --a small cake soaked in a little warm water is enough to make a large pan of dough rise.
Salaeratus (alternative spelling for "Saleratus"): Aerated salt; a white crystalline substance having an alkaline taste and reaction, consisting of sodium bicarbonate.
