I have never seen any KA flour at any Costco out this way!
If you are in a hurry and have not tried the KA "Pizza Flour" give it a try. Makes a very good crust in as little as a couple of hours. It has baking soda added which helps with the quick proof and bake.
I always follow the recipe on the bag of KA "00" flour, Mix it up and let it ferment overnight and bake the next night and the response from Mrs IB is pretty much like this......
Two weeks in my normal schedule but I didn't feed before we went out to SoCal and then when we got home my father's day "present" came 4 weeks early..........
Which necessitated us cleaning out the garage (bigly) in order to fit everything into place. Luckily we are in our hot/dry season...
