These hand-pulled noodles are named after the sound they make as thick lengths of dough are stretched and 'bang-banged' on the work surface by highly skilled noodle chefs in the ancient city of Xian, northern China. They're incredibly satisfying to make, and the moreish, chewy texture with the simple and delicious seasoning of sizzling hot oil poured over garlic and dried chilli makes them equally satisfying to eat!
