Its not somuch about being fast or simple its more about going the extra mile in order toreach top quality. The dough kneaded by hand after machine premix insures forone, all ingredients is completely worked through in the dough; to the other itgives more density to the dough.
As said itis may not really important but it’s the extra mile, why concerning plating, itmakes to the taste no difference if you just pot turn over it.
It’s sureaffects the texture and density. You will see the difference once you roll outthe dough. If finished by hand kneaded the structure becomes more even and homogenous.
Resting thedough for period of time do similar, the dough “relax” and gets elastic by theadjustment and reaction of the mixture as eggs ( water, fat, minerals, aminoacids, vitamins) and flour, most flour today contains added ascorbic acid forkneading tolerance and other additives depending on the flour or purpose of thedough chosen.
Just watchGrant Lee in the video, he is kneading it perfectly just like a baker would do.
@Brandonyour right its Nick G, Sorry Nick I guess I have seen to many vids with Grant working onthe table. Was watching the pastt through.
