I used to bake all the time with regular all purpose flour then when gluten free came into the picture it was not so fun anymore and highly expensive just to do trial foods. (glutenfreeonashoestring.com)
And people also had success using regular all purpose flour instead of the self - rising flour. (mybizzykitchen.com)
I haven't tried it but the all - purpose gluten - free flour I use says it's a 1:1 swap for regular all purpose flour so it should work. (thewannabechef.net)
