OK, I'm curious now. What was the point of stomping the dough if you were to use a rolling pin after?

I think she should have stomped them bare feet.

Now giving the image a second look I notice the dough looks covered with plastic. So she knead the dough with her feet then use the rolling pin to flatten it. Makes sense.

I know I posted too much but this video clearly illustrates what Jintsuu was doing. I think I could put it into practice.
