Hue street vendors serve common dishes, which they make with the same sophistication as delicacies found; in the luxurious "royal meals" served at expensive restaurants and five-star hotels. For example, a Iui spring roll costs only 2,000 VND ($0.13) on the street.
However, the complete dish is by no means simple. Cooks make the rolls themselves from ground lean pork mixed with fish sauce and powdered grilled rice, but they may use dozens of ingredients — such as pig livers, flour, sugar, fish sauce, soy sauce, and coconut milk — to concoct the thick, aromatic sauces for dipping the spring rolls. Other typical and cheap Hue specialties include mussel rice, Hue noodle soup, and canh noodles.
These foods may also have royal origins. Some of the court chefs took palace tride secrets back totheir home villages. As a result, some villages began to specialise in certain dishes; soon, the refined cuisine of the court became popular among ordinary people. For this reason, even poor Hue residents may favour a high-class eating style.
