Sourdough

"I made a splendid batch of bread the day we came.... Besides the bother of making bread so often, we have to make the yeast here about once a week. It’s made of potatoes, hops, salt and sugar. One cupful of old yeast is put into it to start the new batch, which is then put away to rise in a large stone jar in a cool place.” Those were the words of Ethel Hertslet, an Englishwoman who arrived in Lake County, California, in 1885, who was learning how to make bread with sourdough.
