Sanghwabyeong (상화병, Goryeo Fermented Wheat Bun)

Do not let the modern hoppang crowd this old bun out of its own name. Sanghwabyeong is its elder: wheat dough raised with rice wine, filled, rounded by hand, and cooked for a table that had reason to pause. Wheat was not everyday flour in old Korea. That alone tells you this was occasion food, not something grabbed in a paper sleeve on the way home.

Master Seong-nyeo taught it from records and from dough, which is the only way an old recipe becomes food again. She made me smell the makgeolli, then weigh it. A lively bottle gives the dough a small sour sweetness; measured yeast keeps the promise when the bottle is weak. 손맛 is real; I measure it anyway.

The old records don't hand us one neat red-bean formula. They hand us a method: wheat dough, rice wine, a filling, a covered pot. I use pat (red beans) because it belongs naturally to Korean holiday sweets and because it teaches the filling properly. Keep it thick and cool, or it tears through the dough. Pinch the seam closed firmly. Don't lift the lid while the buns cook. The dough is pale, so color won't tell you. Touch will: it should spring back gently and feel light in the hand.
