Hoppang (Sweet Red Bean Steamed Bun)

Ingredients

Equipment Needed

• •Digital kitchen scale
• •Rolling pin
• •Steamer basket or bamboo steamer with lid
• •Clean kitchen towel for wrapping the lid
• •8 parchment squares, about 3 inches / 8 cm each

Instructions

1. 1

   Portion the filling

   Divide the chilled sweet red bean paste into 8 portions of 45g each and roll them into balls. If the paste slumps instead of holding its shape, cook it in a small pan over medium-low heat for 6 to 8 minutes, stirring, until a spoon dragged through it leaves a clear path for 2 seconds. Cool it completely before shaping. Loose filling leaks, and no careful pleat can save it.

2. 2

   Mix the dough

   Whisk together the flour, sugar, baking powder, and salt in a bowl. Add the warm water and oil, then stir until the dough gathers into rough pieces. The water is warm to help the flour soften, not to ferment anything; this is the quick home version, closer to winter hoppang than a long-risen jjinppang.

3. 3

   Knead until smooth

   Knead the dough on the counter for 6 to 7 minutes, using only a light dusting of flour if it sticks badly. It should become smooth, soft, and barely tacky. Smooth dough makes smooth skin, and hoppang is not kind to lazy kneading. Cover and rest it for 20 minutes so the flour hydrates and the dough rolls without shrinking.

4. 4

   Divide and roll

   Divide the rested dough into 8 pieces, about 65g each. Keep them covered while you work. Roll one piece into a 10 to 11 cm circle, leaving the center a little thicker than the edge. The thicker center carries the filling; the thinner edge seals without becoming a lump at the bottom.

5. 5

   Fill and seal

   Place one 45g ball of red bean paste in the center. Gather the dough up around it, pleating as you go, then pinch the seam shut firmly. Turn the bun seam-side down on a parchment square and cup your hand around it, rolling lightly to make a round shape. Do not trap a large pocket of air over the filling, because it expands and wrinkles the bun.

   Write down the filling weight if you change it. More than 45g tastes generous, but it makes sealing harder and the dough cooks unevenly. 손맛 is real; I measure it anyway.
6. 6

   Rest and prepare

   Let the shaped buns rest for 10 minutes while you bring 5 cm of water to a steady simmer in a steamer pot. Wrap the lid in a clean kitchen towel and tie the ends up away from the burner so condensation does not drip onto the buns. This corner is safe to modernize: a metal steamer, bamboo steamer, or electric steamer all work. The seal and the dough thickness are the parts you don't shorten.

7. 7

   Steam the buns

   Set the buns in the steamer at least 3 cm apart. Cover and steam over medium-high heat for 12 minutes. Do not lift the lid early. The dough needs steady heat to set, and a sudden chill makes the surface collapse. Turn off the heat and wait 3 minutes before opening the lid.

8. 8

   Serve while hot

   Lift the buns out with their parchment bottoms. The surface should look smooth and matte, and the dough should spring back when touched lightly. Eat them while the red bean is warm and soft. This is not a plated dessert. It belongs in two hands, on a cold walk home.

Chef Tips

• •Buy thick red bean paste labeled pat-anggeum or danpat. Canned sweetened red beans for patbingsu are usually too wet; cook them down until thick before using or the bun will split.
• •A digital scale matters here. One spoonful more filling looks harmless, but it changes how the dough stretches and seals. This is why old recipes that say 'a lump of paste' fail in another kitchen.
• •Do not over-dust the counter. Extra flour makes the seam dry and stubborn, and dry seams open in the steamer. Use just enough flour to keep the dough moving.
• •Leftover cooked hoppang can be refrigerated for 3 days or frozen for 1 month. Reheat refrigerated buns in a steamer for 5 minutes, frozen buns for 10 to 12 minutes, until the center is warm.

Advance Preparation

• •The red bean filling can be portioned into 45g balls up to 3 days ahead and kept covered in the refrigerator. Cold filling is easier to wrap cleanly.
• •Do not mix this baking powder dough far ahead. Make, shape, and steam it the same day, because the lift weakens as the dough sits.
• •Cooked buns freeze well after cooling completely. Freeze them on a tray first, then bag them so they do not crush each other.
