Jayeondo Salt Bread in Seongsu 자연도소금빵in 성수

The crust is what sets this Seongsu shop apart: baked harder and crisper than most salt rolls, it shatters in thin flakes over a chewy, moist center. It is the only product, sold as takeout in sets of four on Yeonmujang-gil. French AOP butter makes up a large share of the dough, so it eats richer than a bread roll, more like a dessert.
