Mix together all ingredients for about 5 minutes until dough is smooth and elastic.
Roll dough into a long sausage, of about 7cm diameter.
Cut into slices about 1cm thick.
Wrap in plastic wrap to prevent it drying out while you assemble the dumplings.
Assemble Dumplings:
Take one slice of dough and roll it out to a circle about 10-15cm diameter, using the extra rice flour to prevent it sticking to your bench and rolling pin.
Place 2sp filling in the centre.
Pinch together opposite sides of the circle to form a parcel.
Place in steamer.
When steamer is full, steam dumplings for about 7-9 minutes (until cooked through), depending on their size.
