Roll out the pastry to a thickness of a penny, then use a 2 3/4 inch diameter circular cutter to cut out as many pastries as possible. Set the pastries aside on a baking sheet or tray and cover with a tea towel until needed
For the filling, put the noodles in a bowl, cover with hot water and soak for 3 minutes

Combine the dipping sauce ingredients in a small bowl or ramekin and then wrap the dumplings.
Place 1 teaspoon of the filling in the centre of each circle of dough. Fold the bottom centre over the filling to form a semicircle and pinch the top tight.
Pinch the two corners of the semicircle together leaving two symmetrical 'Mickey Mouse ear' shapes between your centre fold and the corner folds.
Now pinch the 'ears' in towards you to make four layered folds
Tidy up to create a 'half-moon' shape and arrange on a plate.
Half-fill a large pot, wok or deep-fryer with vegetable oil and heat to 375ºF, or until the tip of a wooden chopstick or skewer starts to fizz after a second or so in the oil.
Carefully add the dumplings in batches of no more than 10 and deep-fry for 3 minutes, until golden brown.
Remove the dumplings carefully with a slotted spoon and drain well on a plate covered with kitchen paper. Serve immediately with the dipping sauce.
