Soda bread Soda bread Soda bread is a variety of quick bread traditionally made in a variety of cuisines in which sodium bicarbonate (otherwise known as "baking soda", or in Ireland, "bread soda") is used as a leavening agent instead of the traditional yeast. The ingredients of traditional soda bread are flour, baking soda, salt, and buttermilk. The buttermilk in the dough contains lactic acid, which reacts with the baking soda to form tiny bubbles of carbon dioxide. Other ingredients can be added such as butter, egg, raisins, or nuts. An advantage of quick breads is their ability to be prepared quickly
Sliced bread was also intended to counteract a rise in the price of bread, caused by the Office of Price Administration's authorization of a ten percent increase in flour prices. In a Sunday radio address on January 24, New York City Mayor LaGuardia suggested that bakeries that had their own bread-slicing machines should be allowed to continue to use them, and on January 26, 1943, a letter appeared in "The New York Times" from a distraught housewife: I should like to let you know how important sliced bread is to the morale and saneness of a household.
