A pineapple bun, as known as Rocky Bun, is a kind of pastry that is popular in Hong Kong, and some other areas in southern China. It is known in Cantonese Chinese as "bo lo baau" , in which "baau" refers to a kind of bun-like item in Chinese cuisine. "bo lo" means "pineapple", however the traditional version of this pastry contains no pineapple. The name "pineapple bun" actually originated from the fact that the checkered top of the pastry looks like the epicarp of a pineapple.
