Baking Powder. No. 1. (Lady Wensleydale. From Dr. Alfred Taylor.)
Ingredients: 5 ozs. pure bicarbonate soda finely powdered, 4 ozs. pure tartaric acid also finely powdered, 1½ ozs. ground rice.
These 3 things to be thoroughly mixed together with an ivory or a wooden knife (on no account with metal), and then to be kept in a wide-mouthed glass bottle with glass stopper (not a cork) in a cool, dry place.
It is better only to mix enough for a week, or the ingredients neutralize one another.
¾ oz. is the quantity used to each lb. of flour, for baking.
