Jiaozi
A hot-water dough - flour mixed with water (just-boiled) - for a tender, slightly stretchy wrapper that doesn't dry out. The filling is the classic family recipe: minced pork and finely chopped Chinese chives bound with soy, sesame oil, ginger and shaoxing wine. Each dumpling rolled thin, filled with a generous teaspoon, pleated along one edge, sealed and shaped. Boiled in batches, with the "three-cup" trick of adding cold water between waves to stop the wrappers blistering. Served with a sharp black vinegar and chilli dipping sauce.
