Pineapple buns (or buo luo bao / 菠蘿包 in Cantonese) are a popular bun in Hong Kong. If you have been to Chinatown and have tried authentic Cantonese dim sum, you will probably know pineapple buns. Regardless of its name, there is no pineapple in the bun — it's a soft bun with a sweet and crusty topping, which is extremely tasty when it’s freshly baked.
