                Edna Lewis trained Peacock's palate to detect the metallic undertones that commercial baking powders can impart, and he's never looked back. Here's their formula.

                    Cooks' notes: Baking powder keeps in a cool, dark place 6 weeks.
Homemade baking powder can be used in any recipe calling for commercial baking powder (and in the same quantity).
