What makes this odder is that while Cantonese boluo buns contain naisu, BBQ pork, and a bunch of other flavors, there's no pineapple at all. Some say, though, that Taiwanese boluo bun is an evolution of Japanese Hami melon buns, which have the same kind of criss-crossed outside and look similar to their namesake Hami melons.
好笑的是，菠羅麵包的內餡有奶酥、有叉燒，千變萬化，就是不包鳳梨。也有人說，台灣的菠羅麵包是由日本的哈密瓜麵包演變而來，這種麵包同樣是因為表皮網紋密佈、貌似哈密瓜而得名。
