Japanese Melonpan

These traditional Japanese sweet buns are light and airy. They get their name from the thin layer of cookie dough that is baked on top of the dough, which crackles as it bakes and gives them the appearance of a melon. In this version, the delicate cookie dough that covers the sweetened yeast dough is flavored with lemon juice and zest for a bit of tartness that perfectly accents the sweetness of the dough.
