Exactly as printed, 1905
Fermented bread is sometimes considered unwholesome. Those who are of this opinion may make their bread as follows: Mix 1 ounce of bicarbonate of soda with 8 pounds of flour. Stir 1 ounce of hydrochloric acid with 4 pints of warm water. Stir the liquor into the flour briskly, and with a wooden spoon, till the ingredients are thoroughly blended; divide the dough into loaves, and bake these immediately in a brisk oven. It will need to bake as long as bread usually does.
