I understand borax is sometimes used in small amounts in hand-pulled
noodles in China, and I think it may appear in some of the wheat-dough
recipes for mantou in "A Soup for the Qan," although I could be
remembering that last part incorrectly.
I believe it's roughly akin to baking soda in pH, and it can be used
industrially as an antifungal, so one possibility is as a yeast
inhibitor, but for all I know it could have something to do with
gluten extensibility, hence its use in pulled noodles.
If that's the case, I could see it appearing in bagels for a lighter,
more elastic dough.
Bear? Tag, you're it.

when we all ought to worry about our own souls, and other people's
bellies."
