Melonpan

Melonpan , also called melon bun or melon bread, is a Japanese sweetbun covered in a layer of crispy cookie dough. The texture resembles that of a melon, such as a cantaloupe. It is not traditionally melon-flavored. Melonpan and pineapple bun from Hong Kong are very similar. By comparison, the Japanese style is lighter in weight and taste, slightly drier, and has a firmer outer layer (including top cookie crust) that resists flaking, unlike its Hong Kong counterpart, whose top cookie crust tends to flake easily. The Hong Kong version is also moister and is generally soft on the outside and inside, with a stronger butter flavor. Melonpan consists of two loanwords: the English word melon and the Portuguese word pão, meaning "bread". It is called that because the grid or net-like pattern of the crispy surface looks like the skin of some melons.
