Starter won't double in size with 100% Canadian AP flour
Hi everyone 👋
I am having a problem where my dough won't double in size if I don't use commercial yeast together with my sourdough starter.
My starter is generally pretty active. I feed it twice a day 20g AP unbleached flour and 5g rye flour. It normally triples in size.
To see if the problem is the flour, I tried feeding my starter with only AP flour and noticed it won't double in size either.
I am using Canadian flour from bulk barn, but lately I bought two other options to see if the problem was that specific flour, but got the same results.
This Image shows three starters with three different flours in the morning after I fed it the previous night.
And here I have another attempt. Green is 100% AP flour and pink a mix of AP flour with ONLY A BIT of rye and whole wheat.
Here are the flours I used (besides the Bulk Barn one):
