I would like to ask if it's possible to proof dough using only 1/2 of the flour, then adding the rest of the flour with the rest of the ingredients.
The basis for my question is this video, https://www.youtube.com/watch?v=Ij4snv_9ro4
After quite some time just admiring the above video, it didn't occur to me that no initial rise or proofing was done to the dough after mixing everything as seen in the video: skim milk, flour, yeasted risen very wet dough, and honey, and more water, which was obviously to provide more hydration.
After mixing, a sizeable portion must have been scooped out of the mixer and sent to the pastry sheeter. The next rise was done prior to baking.
