How do I make self raising flour from plain flour and baking powder?

[knittingmum]

Anybody know how much to mix of plain flour and baking powder to make SR flour??

Check the side of the baking powder pot, it used to say on mine but not on the brand i have now

What are you making? I think it's between 1 and 3 teaspoons per 8oz.

ooh, thanks girls! Yes, its on the side of the baking powder. Its 4 tsp per 8oz.
Brilliant!
