How to make it
-Mix the plain flour and salt in a bowl.
-Tip the hot water in quickly and stir furiously with a pair of chopsticks to combine the water & flour. -This will allow the dough to develop its gluten and become nice and elastic and stretchy! (I use chopsticks because they allow me to incorporate everything together really quickly, without things clumping like they would using a spoon or a whisk).
-Add the additional water & vegetable oil and mix until you have a cohesive dough. Wrap the dough in cling film and let the dough rest for an hour in the fridge.
-Once the dough is rested, roll it out into a long cylinder (about 2cm in diameter) and cut the dough into about 30 equal balls.
-Rolling out from the centre (see the video for a demonstration), form thin sheets of dough from each ball. This will be the finished dumpling wrapper. If you want to keep it neat, use a cookie cutter to trim the excess.
-Store by adding lots (like 1 tsp) of flour in between each completed wrapper and stacking.
