Although baking powder may be purchased at various prices, a good grade can be made in the home without much effort and usually for less than that which can be bought ready made. For these reasons, many housewives prefer to make their own. The following recipe tells how to make a cream-of-tartar powder that is very satisfactory.
Weigh all the ingredients accurately. If the cream of tartar and the bicarbonate of soda are to be purchased from a druggist, it will be better for him to weigh them than for the housewife, as he uses scales that weigh accurately.
After all the ingredients are weighed, mix them together thoroughly by sifting them a number of times or by shaking them well in a can or a jar on which the lid has been tightly closed. The baking powder thus made should be kept in a can or a jar that may be rendered air-tight by means of a lid, or cover.
