Flour amounts in most yeast bread recipes are suggestions, not exact amounts. The amount you use will be very variable according to the moisture in the air on the day you're making the bread. I use a Bosch, so I just go by adding flour until the dough no longer sticks to the mixer, but by hand, you sort of have to go by the recipe as a guide, go by feel, and add more as needed. If it's too sticky or moist, by all means add more
. Another thought --how coarsely or finely are you grinding the flour? On my nutrimill, when I'm doing bread flour, I just put the dial on about the 10 o'clock position, and that seems to work fine (no pun intended
).
