Smith also sold a baking powder replacement, in which sodium acid pyrophosphate was already mixed with bicarbonate of soda and cornstarch. Somewhat confusingly, it was marketed as "Bakewell Baking Powder" or "Bakewell Cream Baking Powder". Some packaging uses the phrase "The Original Bakewell Cream". A product labelled "Bakewell Cream" may be either the cream of tartar substitute or the baking powder substitute depending on whether it is additionally identified as "Double acting" "Baking Powder". A modern version containing acid sodium pyrophosphate, sodium bicarbonate and redried starch, is sold as being both aluminum-free and gluten-free.
