Recipe by McCarthy
Taken from 'Baking and Desserts' cook book - Food Fact ; Baking powder is a chemically prepared raising agent consisting of cream of tartar and bicarbonate of soda, which is then mixed with a dried starch or flour. It is very important to measure accurately, otherwise the mixture could either not rise, or rise too quickly and then collapse and give a sour taste to the dish.
