How to make the dough
A true sfoglina – this is the Italian name for those women whose expert hands roll out the almost transparent sheet of dough for making stuffed pasta specialties - would probably be horrified to hear their pasta dough being compared to that of a Chinese dumpling. But in both cases, we are talking about a sheet of pastry.
The tortellini is made from 00-type flour and eggs, while our Chinese cook uses plain flour either on its own or mixed with rice flour, with nothing else but boiling water. In the Bologna area, the pasta dough has to be so transparent that "it is possible to see the bell tower of San Luca through it" when you hold it up. Instead, the dough used for Chinese dumplings is thicker.
How to use the rolling pin
Traditionally, in the region of Emilia, the rolling pin is of fundamental importance and any future housewife must have one made especially for her, as part of her dowry. It is about 70 centimeters long and made from heavy beech wood.
The Chinese rolling pin is smaller and easy to handle, no longer than the width of a palm because the sheet of dough is never rolled out whole but in numerous little rounds, one at a time.
How to fold tortellini and dumplings
Chinese jiaozi have many different variants but, for our purposes, we shall be considering the ones filled with meat such as beef or minced pork, combined with Chinese cabbage or nappa, chopped leak or spring onion, garlic, rice wine and sesame oil.
There are many different schools of thought about the authentic tortellini filling, but we shall consider the one approved by the Tortellino Confraternity which harks back to the most ancient recipe. This stuffing is made up of roast pork, Parma ham, mortadella, eggs and Parmesan cheese.
How to shape tortellini and dumplings
To make tortellini you start out from an extremely thin 3 cm square of rolled out dough which is then folded over into a triangle and wrapped around one finger.
The jiaozi are made from a little circular piece of dough, thicker in the centre, which is then sealed by pinching together its edges at the top.
