Put the flour into a heatproof bowl. Pour in hot water (soon after being boiled). Stir with chopsticks or a fork until the flour turns into small lumps.
As soon as the mixture becomes cool enough to handle, knead the mixture into a soft, smooth dough (see note 2).
Cover the dough tightly with cling film. Leave to rest for 15 minutes.
Prepare the filling
Heat oil in a skillet over high heat until very hot. Pour in the beaten eggs and scramble until they turn solid. Once they cool down a little, chop into small pieces.
Soak mung bean vermicelli in hot water for 5 minutes until pliable. Rinse under cold water, then chop the strands into tiny pieces.
Put the chopped chives, vermicelli and eggs into a mixing bowl. Stir in salt and ground Sichuan pepper (or five-spice powder, ground white pepper).
Assemble the pockets
Divide the dough into 12 equal portions.
Dust the working surface and the rolling pin with a little flour to prevent sticking. Flatten each piece of dough into a round wrapper, about 6 in / 15 cm in diameter.
Place the filling mixture in the middle of a wrapper then seal it into a semi-circle flat pocket (see note 3)
Fry the pockets
Fry the assembled pockets in two batches. Pour 1 tablespoon of oil into the skillet over medium heat.
Place in 6 chive pockets then cover with a lid. Flip over when the first side becomes golden brown.
Fry the other side uncovered until it turns golden brown (see note 4).
Make ahead
Freeze uncooked chive pockets on a lightly floured tray. Once completely frozen, transfer them to an airtight bag and store in the freezer for up to three months.
Fry the frozen pockets without defrosting them first. When frying the first side, add about ½ cup (120 ml) of water and cover the pan with a lid.
Notes
1. Mung bean vermicelli noodles don’t have much of a flavor on their own, but they provide an interesting texture to the filling. You may skip them if not available. In this case, increase the volume of chive and egg accordingly. 2. The ideal flour to water ratio may vary slightly depending on the brand of the flour and how you measure it (Measuring with cups is less accurate). 3. Securely sealing the edge of the wrapper is enough, but if you wish to create a prettier pattern, check out my post on Ten Ways to Fold Dumplings which includes a method for these chive pockets.4. Cooking time may vary and a heavy bottom is preferable. It takes me around 5 minutes to cook the first side and a further 2 minutes to finish the other side.
