Wet hands helps with the sticking. Like sloppy wet hands, lol.
Also, having a bread knife really helped me. I didn't have to touch it with my hands all too much.
Oh like the square chopper/scraper things?
That’s the opposite of what I would have thought! You always hear “well-floured hands”
I preach about The Sourdough School book by Vanessa Kimbell all the time, it's such a good resource explaining the how's and why's of sourdough. The water makes the flour slimy, so it slips off.
I’ll be looking into that book, thanks!
