Soda bread. Soda bread (Irish: arÃ¡n sÃ³ide, Scots: fardel, Serbian: Äesnica / ÑÐµÑÐ½Ð¸ÑÐ°) is a variety of quick bread traditionally made in a variety of cuisines in which sodium bicarbonate (otherwise known as baking soda) is used as a leavening agent instead of the traditional yeast.
Notes: A leaven is anything that produces bubbles in dough or batter, causing baked goods to rise. Most breads rise because of yeast, which works by fermenting sugar, which in turn produces carbon dioxide. Baking soda and baking powder are used to leaven quick breads, cookies, and muffins. Baking soda is alkaline and reacts with acid to create carbon dioxide bubbles that become trapped within the batter. It's sometimes used in batters that contain acidic ingredients, like buttermilk or molasses.
