Bread flour has 12.7, AP has 11.7, self rising has 8.5 and their pastry has 8.0.
I like the pastry but can not find it sold in bulk anywhere and while the self rising is grand I am not sure it would store as well.
I never use self rising flour because, I simply don’t use it up quickly enough. I buy the king Arthur flour that is unbleached that our local Walmart has. I’ll have to check to see if they have the various protein counts.
Then I put it into quart mason jars, with Oxygen absorbers and vacuum it with my mason jar adapter for my food saver. I rarely use up a 5 lb. bag in a year’s time.
