Soda bread

Soda bread is a variety of quick bread in many cuisines which uses sodium bicarbonate (baking soda or bread soda) as a leavening agent instead of yeast. The basic ingredients of soda bread are flour, baking soda, salt, and buttermilk. The lactic acid in the buttermilk reacts with the baking soda to form bubbles of carbon dioxide. Optional ingredients include butter, egg, raisins, or nuts. Quick breads can be prepared quickly and reliably, without requiring the time and labor needed for kneaded yeast breads.
