Pineapple Bun - Buttered Variant

Buttered Variant

Many Hong Kong restaurants, such as cha chaan tengs and dai pai dongs, offer an item called a "buttered pineapple bun", which is a pineapple bun with a piece of butter stuffed inside. They are known in Cantonese Chinese as bo lo yau (菠蘿油), in which "bo lo " means "pineapple," and "'yau'" (oil) refers to butter. Variants of this include using custard in place of butter.

Typically, the bun would be brought hot from the oven to the diner's table, and served halved with a large slab of butter in between the halves. This item is sometimes criticised for containing too much fat and cholesterol.
