This week, Bob faces his toughest challenge yet: mastering the lost art of making hand-pulled noodles. This labour intensive technique involves folding, twisting and stretching dough until it separates, as if by magic, into perfectly equal noodle strands. It’s so difficult that only a handful of chefs still do it. Bob will have just one week to learn this complex technique, which most chefs take years to master. At the end of the week, Bob will fly to Hong Kong where he will step into the shoes of the noodle chef at the Lanzhou hand-pulled Noodle King restaurant.
