Yes. I’d always used whatever brand all purpose unbleached flour for the starter and figured it didn’t matter. So I always asked for “Gold Medal Bread Flour and whatever brand all purpose unbleached flour”. But the Publix brand all purpose unbleached wrecked my starter. It took almost the whole bag before I figured out it was the flour, because I didn’t realize they varied.
It’s actually quite good for pancakes. Maybe it’s good for biscuits, that would actually make sense. But it’s no good for bread; but Gold Medal or King Arthur unbleached all purpose work fine.
