Introduction
The Pineapple Bun, or Bo Lo Bao (菠蘿包), is one of Hong Kong’s most iconic pastries, adored for its distinctive golden, crackly crust. Ironically, this sweet treat doesn’t contain any pineapple—the name comes from its sugary topping that resembles the skin of a pineapple. With a fluffy, milky bun base and a crunchy, buttery topping, it’s a staple at Hong Kong bakeries and cha chaan tengs (local cafés).
History & Cultural Significance
The Pineapple Bun emerged in 1940s Hong Kong, a time when local bakers began experimenting with Western-style pastries. One popular origin story credits the Ng family, who, after being deported from Mexico, opened a café on Shanghai Street in 1946. They introduced a Pineapple Bun inspired by the Mexican concha. Another account highlights Tai Tung Bakery, founded in 1943, as the first to create what was initially called the “crispy-skin bun.”
This humble Pineapple Bun eventually earned a place in Hong Kong’s intangible cultural heritage in 2014, cementing its role not just as a snack, but as a cherished piece of local history.
