Xíu mại takes its name from Cantonese siu mai, the dim sum dumpling — though in Vietnam it has become a loose meatball in tomato sauce rather than a wrapped dumpling.
Pork meatballs studded with mushroom and onion simmer in a light tomato broth, served in a bowl with a torn baguette for dunking, or with the baguette split and stuffed. Đà Lạt sidewalk stalls sell it hot each morning, a favorite in a town cool enough that a warm bowl actually makes sense at breakfast.
