Instead of cream of tartar and soda, or soda and sour milk, the best housekeepers now use Royal Baking Powder. It is almost impossible for the housekeeper to procure pure cream of tartar. Professor Chandler, when president of the New York Board of Health, stated in an official report that he found upon investigation that nearly all the cream of tartar sold by grocers was adulterated with white clay, alum, or other hurtful substance. These ingredients are dangerous to health, impoverishing the blood, producing dyspepsia, etc. Professor Chandler strongly recommends the use of a well-known baking powder (like the Royal) in all kinds of baking as more convenient, economical, and healthful.
Royal Baking Powder is sold only in securely labeled tin cans.
Remember, in all old receipts where cream of tartar and soda or saleratus are called for, you can substitute Royal Baking Powder and get better results.
The usual proportions, old way, are: 2 teaspoonfuls cream of tartar to 1 of soda or saleratus;
Instead of which use 2 teaspoonfuls of Royal Baking Powder, and mix it with the flour while dry. This powder is so pure and perfectly combined that one third less will do better work.
Never use so-called prepared or self-raising flours. They mostly contain alum, phosphates, or other injurious ingredients.
THE OFFICIAL TESTS

The United States Government, after elaborate tests, reports the Royal Baking Powder a pure cream of tartar powder of greater leavening strength than any other.
