Patjuk (Korean Red Bean Porridge)

In Korean cooking, patjuk sits somewhere between a warming porridge and a gently sweet dessert, made from adzuki beans simmered until soft and worked into a smooth red bean base. Straining out the skins gives the porridge its characteristic silky texture, while small rice-flour dumplings add a soft, chewy bite as they cook directly in the simmering mixture. Often associated with colder weather and winter-solstice traditions, it is enjoyed for its earthy bean flavour, mellow sweetness and comforting warmth. Serve it plain and warm, adjusting the sweetness to suit the occasion.

Why this recipe works

  • Smooth bean base: Pressing the cooked adzuki beans through a sieve removes the skins and gives the porridge its characteristically silky texture.
  • Soft dumpling contrast: Rice flour dumplings cook in the porridge itself, adding a tender, gently chewy bite against the smooth red bean base.
  • Gentle sweetness: The sugar is added at the end, making it easy to adjust the sweetness without masking the natural earthiness of the beans.

Authenticity notes

  • Winter tradition: Patjuk is closely associated with Dongji, the Korean winter solstice, though it is also enjoyed more broadly as a warming sweet porridge.
  • Sweet or lightly seasoned: Some versions are kept less sweet and seasoned more simply with salt, while dessert-style patjuk leans gently sweet as in this recipe.

Ingredient notes

  • Use adzuki beans: Adzuki beans give patjuk its distinctive colour, earthy flavour, and smooth body once cooked and strained.
  • Rice flour choice: Standard rice flour makes softer dumplings, while glutinous rice flour gives a chewier texture that stays more elastic.

Texture tips

  • For a silkier porridge: Press the beans thoroughly through the sieve, taking time to extract as much purée as possible while leaving the skins behind.
  • Keep the heat gentle: Once the bean purée is added back to the liquid, simmer gently and stir often so the porridge thickens evenly without catching.
  • Cook dumplings fully: The dumplings should float and feel tender throughout before serving; smaller dumplings cook more evenly.

Make-ahead tips

  • Make the base ahead: The red bean porridge base can be prepared in advance and refrigerated, then reheated gently with a splash of water.
  • Dumplings are best fresh: Rice flour dumplings soften after chilling, so add and cook them close to serving if you want the best texture.
  • Reheat slowly: Warm leftovers in a saucepan over low heat, stirring often and loosening with a little water as the porridge thickens in the fridge.

  1. Rinse the adzuki beans, then put them in a large pot with the water. Bring to the boil, boil for 5 minutes, then drain and return the beans to the pot with fresh water from the measured amount. Bring back to a gentle simmer.
  2. Simmer the beans over low heat until very soft and starting to split, topping up with a little more water if needed to keep them submerged. You want them tender enough to mash easily between your fingers. This usually takes 45 to 55 minutes.
  3. Set a sieve over a saucepan and strain the beans, catching the cooking liquid. Push the beans through the sieve with a wooden spoon to extract as much smooth bean purée as you can, leaving the skins behind. Stir the purée into the reserved liquid in the saucepan.
  4. Bring the red bean base to a gentle simmer and cook, stirring often, until it looks slightly thickened and silky. If it becomes too thick, loosen with a splash of the remaining water; if too thin, simmer a little longer. Keep the heat low to prevent catching.
  5. Meanwhile, put the rice flour in a mixing bowl and stir in the fine sea salt. Add just enough water to form a soft, pliable dough that holds together without cracking. Roll into small dumplings about the size of a marble.
  6. Slip the dumplings into the gently simmering porridge and stir carefully so they do not stick to the bottom. Simmer until the dumplings float and feel tender throughout, 3 to 5 minutes. Keep the porridge at a gentle bubble so the dumplings cook evenly.
  7. Stir in the caster sugar and simmer for 1 to 2 minutes, just until dissolved. Taste and adjust with a little more sugar if you like it sweeter. Serve warm.

Recipe notes

Tips

  • For a smoother porridge, take your time pressing the beans through the sieve; the more you extract, the silkier the base will be.
  • Keep the heat low once the bean purée is in the pan and stir regularly, as the porridge can catch on the bottom as it thickens.
  • If serving to young children or anyone who struggles with chewy textures, make the dumplings slightly smaller so they cook through quickly and evenly.

Substitutions

  • Replace caster sugar with granulated sugar for a slightly less quick-dissolving sweetness; simmer an extra minute to ensure it fully dissolves.
  • Replace rice flour with glutinous rice flour for chewier dumplings that stay softer as the porridge sits.

Storage

  • Refrigerate up to 3 days
  • Cool, then refrigerate in an airtight container for up to 3 days. Reheat gently in a saucepan with a splash of water, stirring often, until piping hot; the porridge will thicken as it stands. The dumplings are best fresh and can become overly soft after chilling.
