Brown Soda Bread is a traditional Irish bread made using whole wheat flour, baking soda, salt, and buttermilk. Unlike yeast breads, it relies on the chemical reaction between baking soda and the acidity of buttermilk for leavening, resulting in a dense and hearty texture. This bread is often enjoyed fresh, served with butter, or used as a side for soups and stews. Its nutty flavor and rustic appearance make it a popular choice in Irish cuisine, and it can be easily prepared at home with minimal ingredients and time.
