The next step is to make the dough. Pour all-purpose flour/plain flour into a bowl. Add sugar, cooking oil, water, stir while pouring. Then knead into a dough. This is a medium soft dough, cover and lets it rest for about 10 minutes. After 10 minutes, continue to knead the dough, it will become smooth after a few times. Cover the dough and let it continue to rest for about 30 minutes.
