Combine all of the above ingredients in a mixing bowl
Whisk until fully mixed. Pour into a steaming pan the batter will be very thin and runny
Cover the pan with a plate or tin foil so that steam doesn’t get on the batter
Steam on high for 20 minutes. My batter was approx. 1.5” in height. If you’re steaming pan is wide, you may use less time. It’s cooked when it’s not runny
When time is up, score the dough and loosen it from the pan. It will be sticky and it’s fine if it looks roughed-up
Let it cool for 15-30 minutes. You can start kneading it when it’s still warm. Just don’t burn yourself. Be sure to wear plastic food gloves because the dough is quite sticky
Knead until soft, smooth and elastic. Will take approx. 5 minutes
Put in a zipper bag or wrap in plastic wrap and cool in the refrigerator for 30 minutes
After 30 minutes, dough skin is ready to use Note that the dough is now cooked and ready to eat
