That, and the dough is covered with clothes too, so basically the dough didn't come directly into contact with their bare skin (which is a shame, dangit..!) Jokes aside, kneading the dough with feet will make the result chewier, or so the teuchi udon recipe said.. Perhaps the same principle could apply to somen too..
The next dayI too will be helping with this~This is delish~It's to take Kitakami's attention-kuma...Oh....Heh......Now we only have to let it dry up for one night. It's good but is there any need to go out of the way to make it herself-nya...?This year too, I shall be looking forward to the Nagashi-soumen fes! Tada!Kitakami-san~ ❤Today's dinner is the soumen we made together yesterday ❤!When you talk about summer then it must be soumen right ❤.
