Buttermilk is primarily due to lactic acid produced by lactic acid bacteria while fermenting lactose, the primary sugar in milk. As the bacteria produce lactic acid, the pH of the milk decreases and casein, the primary milk protein, precipitates, causing the curdling or clabbering of milk. This process makes buttermilk thicker than plain milk. While both traditional and cultured buttermilk contain lactic acid, traditional buttermilk tends to be less viscous, whereas cultured buttermilk is more viscous. Buttermilk can be drunk straight, and it can also be used in cooking. Soda bread is a bread in which the acid in buttermilk reacts
Stoneground flour Stoneground flour Stoneground flour is a wholemeal flour produced by the traditional process of grinding grain between two millstones, in contrast to mass produced flours which are generally produced using rollers. The process leaves the wheatgerm more intact than roller processes for producing wholemeal flour, the larger pieces of bran and other components of the grain cause it to have a coarser texture but greater flavour. This affects its ability to rise, however it can produce a more satisfying texture for some baked products. The inclusion of more bran and intact wheatgerm in the flour means that it is often
