Bún riêu

Bún riêu is a traditional Vietnamese soup of clear stock and rice vermicelli. There are several varieties of bún riêu, including bún riêu cua , bún riêu cá (minced crab and fish) and bún riêu ốc (minced crab and snail). Bún riêu cua is served with tomato broth and topped with minced freshwater crab. In this dish, various freshwater paddy crabs are used, including the brown paddy crab found in rice paddies in Vietnam. The crabs are cleaned to remove dirt and sand, then pounded together (with the shell still on) into a fine paste. This paste is then strained — the liquid becoming the base for the soup along with tomato, and the solids used as the basis for crab cakes. Other ingredients for this dish include tamarind paste, fried tofu, mẻ or giấm bỗng (kinds of rice vinegar), quả dọc (Garcinia multiflora Champ.), annatto seeds (hạt điều màu) to redden the broth, huyết (congealed pig's blood), split water spinach stems, shredded banana flower, rau kinh giới (Elsholtzia ciliata), spearmint, perilla, bean sprouts and chả chay (vegetarian sausage). This dish is rich in nutrition: calcium from the ground crab shells, iron from the congealed pig's blood, and vitamins and fiber from the vegetables.[citation needed]
