Soda breads are hearty Irish staples - wholemeal flour with large flakes of bran and wheat germ, or white flour or a mixture leavened with baking soda and moistened with buttermilk. The acid in the buttermilk reacts with the baking soda, which is an alkali, creating bubbles of carbon dioxide which rise the bread. Soda breads have the heft of a yeast bread but are made in minutes and the dough can be shaped into scones or a round loaf, depending on the occasion. Originally it would have been baked in a bastible (pot oven) over the open fire.
