Phở xào (“fried rice noodles”) is a speciality of Hanoi. It’s made by frying noodles with beef and Brassica rapa. There are two types of fried noodles: khô (“crisp”) or ướt (“moist”), the difference being due to the frying time of the noodles. A gravy-like sauce made with fried beef is poured over the noodles. It’s served with pickled cucumber and carrot slices.
