Hanoi rooftop spring rolls (nem rán)

Nem is one of the most popular culinary exports from Vietnam. Chances are you have tried one even if you have never set foot in a Vietnamese restaurant. In Vietnam, they are called chả giò, or nem rán (literally meaning ‘fried sausage’) in the North. Freshly made and dipped in strong nước mắm pha dipped sauce, they are still one of my favourite things about Vietnamese street food. These ones from Phuong are the best we have had so far.
