Raising Agents
The raising of materials to be cooked is accomplished by fermentation, as with yeast; by entangling air in the mixture as by beating; and by chemical action as in the case of the Soda combinations. The last means and in that we are most interested-is far the simplest, doing away with the wearisome waiting for the yeast plant to grow, and the beating that makes one's arm ache to think of. In using this third method the mixture is rendered porous by the action of certain acids, contained either in food as sour milk or molasses, or furnished by a chemical like cream of tartar, which frees the carbonic acid gas in the Soda.
Baking powders are made by combining Soda with cream of tartar, a chemical so expensive as to offer strong temptation to the manufacturer to adulterate his product. An eminent chemist, after analyzing fifty different brands, found that fifty per cent were grossly adulterated. As the sole value of baking powder is the raising property, or carbonic acid gas, which is contained in the Soda alone, the safest and most economical plan is to secure a brand of Soda above suspicion of impurity, wrapped so as to insure its continued strength. Then if baking powder is needed for any purpose, it can be made at home and its quality and healthfulness assured. Soda, unlike baking powder, is cheap. Cleanliness in the handling and careful wrapping bring to you a wholesome, powerful raising agent. Such, The Great Arm & Hammer Soda has been found to be by purchaser and chemist alike. There can be no doubt about The Great Arm & Hammer Soda. It has stood for years as the standard of Soda excellence. Its reputation is too valuable to risk: you may use with perfect confidence the Soda that comes to you sealed in packages bearing The Great Arm & Hammer trademark. It contains uniformly over 52% of carbonic acid gas and over 99% of pure Soda, every pound of which is tested before leaving the extensive chemical works of the manufacturers, and not permitted to be sold unless up to this standard.
The strength of The Great Arm & Hammer Soda is maintained by careful wrapping in distinctive packages for the greater security of our patrons. And although The Great Arm & Hammer Soda is also sold in kegs to supply a certain demand, we advise against buying it in bulk for the reason that it makes substitution an easy matter. Be sure you see the circles of blue and red enclosing the Arm and Hammer and the firm name, Church & Co. Then neither accident nor design. can prevent your getting the best Soda made or possible to be made.
