Place flour and hot water into a bowl and stir until just combined.
Pour onto clean surface and knead for 6-8mins until dough is smooth. Add tsp flour or water at a time if dough is too wet/dry. Shape into ball and leave to rest for 30mins (meanwhile prep your filling).
Divide dough into 20 to 24 even disks (depending on how big you want your dumplings to be). Dust with flour and flatten disks.
With a small rolling pin, roll towards the centre of the disk, only applying pressure going inwards (this allows the centre of the wrapper to be thicker and the edges thin). Rotate disk 45 degrees and roll towards the centre of the disk, again only applying pressure inwards. Repeat until wrapper is around 1mm thick. Make sure the wrappers are well floured to prevent sticking.[alternatively, you can just roll out the entire dough ball and use a cookie cutter to form wrappers]
