Step 3
Mix the fresh milk with the mashed potato and sugar, then pour into the flour. Use a rubber spatula to bring together into a dough—do not overmix to avoid developing gluten. Transfer to a floured surface and dust the top of the dough with a little flour to prevent sticking.

Step 4
Dust the rolling pin with flour and roll the dough out to about 0.8 cm thick. You may also use the palm of your hand to press it flat, but be sure to dust both hands with flour to prevent sticking. Cut the dough into rectangles about 4 cm x 6 cm.
