Yes they are the same.

I was thinking about the same thing over Xmas as I was reading some simple recipes before deciding to make shortbread biscuits. I think All purpose are from the UK or U.S recipes on how they write plain flour . If it is written here, it always states SR or Plain so not really sure .

Yes, they’re the same thing. I’m pretty sure that the Americans call Plain Flour, All Purpose. It’s a bit confusing.

Thank you very much for your help x

It’s not a dumb question All purpose flour is what the Americans call plain flour.

Yes they are the same. Plain flour is called all purpose flour in America

Thank you for replying. I did manage to find some all purpose flour in the supermarket.

As far as I know they are the same thing. Some people say all purpose flour is what the American’s call plain flour.
