Irish soda bread is made with baking soda as a leavening agent instead of yeast. In the mid 19th century, Irish bread bakers began to use baking soda to compensate for its lack of hard wheat flour, which requires yeast for leavening, according to the Baking Bits website. Store Irish soda bread at room temperature or in the freezer depending on how long you want to enjoy this hearty bread.
Cut cooled Irish soda bread into quarters or leave it whole for serving purposes and for storage. Completely cook Irish soda bread before freezing.
