*King Arthur Flour gives a fairly wide flour measurement variation for a couple of reasons. First, you’ll find in the summer that you’ll need a bit more flour to absorb a given amount of liquid than you will in the winter. This is because it’s humid and flour acts somewhat like a slightly dampened sponge as a result. I used 6 1/2 cups flour for my hot dog buns.

King Arthur Flour also notes that this particular dough should be quite slack, i.e., very relaxed in order to make soft and tender buns. So you want to add only enough more flour, past the 6-cup point, to make the dough just kneadable; sprinkling only enough more to keep it from sticking to you or the board.
