It’s “bun cha ca” broth, which is made from boiled sailfish and mackerel’s bones, that determines the exclusive taste of this specialty. Different from the fatty boiled pork bones’ broth; “bun cha ca” broth is sweet and savory, especially suitable for people who are going on a diet. A bowl of Nha Trang’s “bun cha ca” also contained jellyfish and steamed sailfish.
