Salt bread, also known as shio pan, is a popular Japanese-style bread roll that has recently surged in popularity across Asia, especially in Korea, where it is now a staple in many bakeries. What makes it so special is its simple yet irresistible design: soft, fluffy dough wrapped around a piece of butter. As it bakes, the butter melts into the bread, creating a shiny golden crust and a rich, crispy bottom. The combination of the light, tender interior and the buttery, salty crunch is what makes salt bread so appealing.
