The Acid    Components  of  Baking

Powders

Some    of  these   acids   are available   only    to

manufacturers.   Most    double-acting

supermarket baking  powders are a   mixture

of   sodium  bicarbonate,    MCP,    and     SAS.

Single-acting    powders     omit    the     SAS,    and

the  MCP     is  coated  to  delay   its     release

artificially.
