[moondog]

Eh?????

Eh????
Tis in American receipt.

bicarbonate of soda: ingredients: bicarbonate of soda
baking powder: ingredients: wheat flour, disodium diphosphate (raising agent), sodium hydrogen carbonate (aka bicarbonate of soda)

Baking Powder:
To use plain flour as a replacement for self raising, add 4 level tsps to 225g flour.

look here

baking soda = bicarbonate of soda. You can make baking powder with bicarb plus cream of tartar in some quantity I can't remember.

Aye but still no clearer.
Will just go for all baking powder I think.

Bicarb: to make a simple baking powder, mix 1 part bicarb to 2 parts cream of tartar (don't ask me about cream of tartar, not got that in baking cupboard)

If the recipe says baking soda, it means bicarb of soda.

Bakibng powder has baking soda plus other stuff.

I feel all faint....

Baking poweder is the same as Bakibng powder

Oh FFS, I'm turning into Cod.

bicard is alkali, and will leave a bitterness in the taste of the baking unless counteracted by acidic substance.
hence baking powder is bicarb plus tartaric acid (cream of tartar or potassium bitartrate)
How I love kitchen chemistry.

if american recipe requires baking soda - use bicarb.
if baking powder, use erm, baking powder

too many cooks methinks.

Tartaric acid being Cream of Tartar right?

Thus baking powder is Bicarb plus Cream of T?? Yes????

Baking powder is sodium bicarb plus something else. It can be cream of tartar.

agree with soupy.
c'mon Moondog, you'll be cooking at midnight at this rate.
