Sift the flour and put it in the mixer bowl, adding the salt and as much water as is needed to make a pliable dough that doesn't stick on the walls of the bowl. Let the dough rest for half an hour covered with a towel. Divide it into 6 equal parts and knead them into balls letting them rest for an additional 10 minutes. Take each ball of dough and dust it with corn starch on both the top and the bottom so that it rolls out easily.
