Although kuay jap yuan itself doesn’t have an exact counterpart in Vietnam, the long, thin, round noodles made from rice flour, cassava (tapioca) flour, and sometimes sticky-rice flour are similar to Vietnamese bánh canh. Unlike most Thai noodle dishes, the noodles are cooked directly in the broth (in this case, a peppery pork-bone broth), their cassava flour dusting giving it a cloudy, slightly viscous texture. The noodles and broth are supplemented with slices of peppery Vietnamese pork sausage, braised pork meat and/or ribs, and sometimes quail egg and shiitake mushrooms; the dish is garnished with deep-fried crispy shallots and chopped green onion. Kuay jap yuan is served with usual noodle condiments, as well as a condiment of dried chili flakes simmered in oil.
