[Sca-cooks] baking powder

[Margaret Rendell]

Now I'm confused.

I've managed to delete the original post, but there was a reference to
'single-' and 'double-acting' baking powder.

I've only ever seen one sort of thing marketed here (Lochac) as "Baking
powder"...bicarb. soda plus a phosphate aerator, plus a filler, usually
rice flour. Four teaspoons of it make a pound of plain flour into a
pound of self-raising flour. Is this 'double-action', and bicarb. alone
'single-action'?
