It may look like a mini croissant, but this Japanese-born treat tastes and feels completely different. Shio pan translates to salt bread; it’s made by wrapping milk bread dough around a log of cold, salted butter that melts into the fluffy bread as it bakes. The result? A crisp golden-brown crust and soft buttery interior that’s salty-sweet and pulls apart, instead of flaking like pastry.
