Dough doesn't ball in mixer
I have a 65% hydration dough (water, flour, levain, salt). I put it in the mixer for 10 minutes (on speed 1, my mixer is Kenwood), and it's just a gooey mess. I've seen videos where even at 70% it balls on the hook. What am I doing wrong?
One thing may be is that I use warm water. Maybe switch to cold?
I've tried using the minimum speed for 5 minutes, let it rest, then on high for 5. I tried the reverse. I tried low-high-low. Always with the same result.
Note it does form a sort of a window pane. So maybe balling on the hook is not something I need to pursue?
