The only raising agent used in this type of preparation is the sodium bicarbonate. The rising is therefore due to the production of CO2 which, in this case, is released in the moment in which the bicarbonate is in contact with the milk. Since this reaction is very fast you need to be quick to prepare the dough so that the CO2 needed to make the bread rise, is not lost in the air while you knead the different ingredients. 
The recipe of soda bread has Irish origin. This type of bread is ideal for a healthy breakfast consisting of bread and jam, or to taste savory dishes during a main meal.
