Irish soda bread is made, as the name suggests, with bicarbonate of soda (also known as sodium bicarbonate). The soda acts as a leavening agent so you don’t need to add any yeast. It doesn’t need to be kneaded really either, so it’s very quick and easy to make. This recipe is for speckled white soda loaf from Country Bread by Linda Collister and Anthony Blake. It’s a bit more special than your average Irish soda bread because it has pieces of dark chocolate added!
