Cao lau
You will really only find proper cao lầu in Hội An, the old trading port on Vietnam's central coast, where it's sold in small family eateries and along the riverside at lunch. The noodles are yellowish and unusually chewy, made with lye water that locals traditionally link to the town's ancient Bá Lễ well. They come almost dry, topped with slices of sweet five-spice pork, raw greens and crisp squares of fried dough, with just a spoonful of the pork juices. Because the real noodles are very hard to buy outside Hội An, this home version uses thick udon noodles, which give a similar bouncy chew; it is a substitute, not the original. Chef's tip: rinse the cooked udon in cold water, then dip briefly in hot water just before serving, so they are warm but firm.
