Why put the flour on the baking paper?
To be honest, I've never seen anyone do that, or heard anyone saying that's a good thing. This was the first time I saw it in this video and usually I'm following the recipe (almost) to the letter, if it's the first time. So I thought, let's try it out. Mine did not burn as it was only 30min at 190°C, but you are right, it can burn easily.
Yeah, kneading is important and trust, me, it's the first time I opted for this no-knead recipe, because my arm was hurting. Otherwise I prefer a kneaded dough, especially that I have a mixer to do the hard work.
I've seen many recipe use the bowl of water when baking, but as this was a fast one, the original recipe says nothing about it, I thought it would be ok without it.
It always works without the addition of water – but the dough is happy with the moist steam.
