On the coldest December night in Seoul, when the wind comes howling down off Namsan Mountain, my mother always put a heavy iron pot of adzuki beans on the stove. By late afternoon, our apartment filled with the deep, nutty, slightly sweet aroma of simmering red beans. We were preparing for Dongji (the winter solstice), the longest night of the year, when tradition says eating a hot bowl of patjuk (sweet red bean porridge) drives away lingering cold spirits and invites good fortune for the coming year.

While custom ties this dish to the winter solstice, every Korean knows that a warm bowl of patjuk is pure soul food whenever you need deep, grounding comfort. Traditional Korean porridge falls into two broad categories: savory meals like abalone or chicken porridge, and warm, dessert-leaning grain bowls like pumpkin porridge or red bean porridge. This version focuses on the velvety, gently sweet style popular in Seoul modern tea houses and home kitchens alike, finished with soft, chewy saealsim (bird’s egg rice cake balls) made from sweet rice flour.

If you have never cooked with dried adzuki beans before, do not be intimidated. This patjuk recipe breaks down the process into clear, simple steps that yield a silky, rich porridge right on your home stove, using standard equipment and easy-to-find ingredients.

Why This Works

• Discarding the first boil: Quick-boiling the raw beans for five minutes and throwing away that initial water removes harsh tannins and saponins, eliminating bitter notes and making the porridge far easier to digest.
• Dual-texture technique: Blending roughly three-quarters of the cooked beans while leaving the rest whole creates a silky-smooth base punctuated by whole, creamy beans for a delightful mouthfeel.
• Hot-water dough doughing (tanjoong effect): Mixing sweet rice flour with hot water gelatinizes the starches instantly, producing saealsim that remain delightfully chewy without breaking apart inside the hot porridge.

Ingredients

• 400 g (about 2 cups) dried adzuki beans (red beans)
• 2.1 liters (about 9 cups) water, divided
• 120 g (about 1 cup) chapssal-garu (sweet rice flour / glutinous rice flour)
• 90 ml (about 6 tbsp) hot water for dough
• 5 g (about 1 tsp) fine sea salt, divided
• 60 g to 85 g (about 1/4 to 1/3 cup) granulated sugar or honey, adjusted to taste
• Optional garnishes: whole pine nuts, peeled cooked chestnuts, or a light dust of ground cinnamon

Substitutions

Dried adzuki beans (sometimes labeled red chori or small red beans) are widely available at Asian markets, healthy food stores, and online retailers. If you cannot find Korean brands like Ottogi or CJ, Japanese azuki beans work identically.

For the chewy rice balls, you must use glutinous rice flour (sweet rice flour). Standard regular rice flour lacks the sticky starch structure required to form chewy dough. Mochiko flour or Bob’s Red Mill Sweet White Rice Flour are excellent substitutes found in most Western supermarkets. In a pinch, if you prefer not to make the rice balls from scratch, you can buy pre-made frozen plain rice cakes (tteok) or serve the red bean porridge entirely plain with a sprinkle of toasted nuts.

How to Make It

1. Perform the initial boil to remove bitterness. Place your dried adzuki beans in a large heavy pot and cover them with cold water by about two inches. Bring to a rapid boil over high heat and let boil for 5 minutes. Drain the beans completely into a colander and discard the purplish cooking water. Why: Raw red bean skins contain bitter tannins and compounds that can irritate sensitive stomachs; discarding this first water guarantees a clean, mellow sweet bean flavor.
2. Simmer until butter-tender. Return the drained beans to the pot. Pour in 1.8 liters (about 7.5 cups) of fresh cold water. Bring to a boil over medium-high heat, then lower the heat to medium-low, cover tightly with a lid, and simmer gently for 55 to 65 minutes. The beans are ready when you can easily crush one between your thumb and forefinger with zero resistance. Why: Cooking red beans slowly at a gentle simmer breaks down their dense inner starches without scorching the bottom of your pot.
3. Make the saealsim (rice cake dough). While the beans cook, place the sweet rice flour and half a teaspoon of salt into a heatproof bowl. Pour in 90 ml of hot water. Mix with a wooden spoon until a shaggy dough forms, then knead with your hands for 2 to 3 minutes until smooth and pliable. Roll the dough into a long log and slice it into small pieces, rolling each piece between your palms into round balls about the size of a marble (roughly 2 cm in diameter). Dust them lightly with a pinch of extra flour so they do not stick together. Why: Using hot water instantly hydrates the glutinous starches, making the dough easy to shape without cracking.
4. Purée the beans for structural balance. Once the beans are tender, turn off the heat. Scoop out roughly one cup of whole cooked beans and set them aside. Use an immersion blender directly in the pot (or transfer the remaining beans and liquid carefully to a stand blender) and process until smooth and creamy. Return the purée and reserved whole beans back into the main pot. Why: Blending most of the mixture creates that luxurious, velvety porridge texture classic to Seoul tea shops, while keeping some whole beans adds satisfying rustic body.
5. Cook the rice balls and finish the porridge. Set the pot over medium heat and bring the purée to a gentle, bubbling simmer, stirring frequently with a wooden spoon. Carefully drop in the shaped rice balls. Stir continuously along the bottom of the pot for 5 to 7 minutes. As the rice balls cook through, they will float to the surface. Why: Continuous stirring is essential at this stage because thick starches sink quickly and scorch easily on the bottom of hot cookware.
6. Season right before serving. Once the rice balls float, stir in the remaining half teaspoon of salt and your desired amount of sugar or honey. Cook for one final minute until the sugar dissolves completely, then remove from heat. Ladle into shallow bowls and decorate with pine nuts, chestnut pieces, or cinnamon if desired. Why: Adding sugar too early in the bean cooking process hardens the bean skins and prevents them from softening properly, so seasoning always comes last.

Continuous stirring ensures smooth consistency without burning.

Tips from a Korean Kitchen

• Use a heavy-bottomed Dutch oven: Porridge thickens significantly as bean starches hydrate. Heavy cast iron or tri-ply stainless steel distributes heat evenly, drastically reducing the risk of scorched porridge on the pot base.
• Adjust sweetness individually: In Korea, traditional home cooks often serve patjuk lightly salted, allowing each family member to add sugar at the table to match their personal preference. If serving this for breakfast or a light supper, keep it less sweet; for a cozy afternoon treat, add a bit more sugar or a swirl of honey.
• Freeze spare rice balls raw: If you double the rice ball recipe, lay unbaked balls on a parchment-lined baking sheet and freeze until solid. Transfer them to a zip-top bag for up to two months. Drop them directly into bubbling porridge without thawing.
• Keep an eye on thickness: As red bean porridge cools in the bowl, it thickens rapidly. If it feels too stiff while cooking, splash in 60 ml (1/4 cup) of warm water at a time until you reach your desired creamy consistency.

Storage

Patjuk keeps remarkably well in the refrigerator for up to 4 days when stored in an airtight container. Keep in mind that the chewy rice balls will naturally firm up as they cool down. To reheat, transfer the desired portion to a small saucepan, add 2 to 3 tablespoons of water to loosen the porridge, and warm gently over low heat while stirring until steaming and soft again.

You can also freeze the base porridge (without the rice balls) for up to 2 months. Thaw overnight in the fridge and simmer on the stovetop, dropping freshly made rice balls in right before serving for the best texture.

FAQ

Is patjuk served sweet or savory?

It can actually be both! Traditional old-style home recipes lean subtle and savory, seasoned primarily with sea salt and eaten alongside sour dongchimi (radish water kimchi). Modern Korean home cooks and café culture generally favor a gently sweet version enhanced with honey, brown sugar, and spices like cinnamon.

Can I use canned red bean paste instead of dry beans?

Canned red bean paste (often called sweet red bean paste or anko) is pre-sweetened and blended very fine with added vegetable gums or oils. It produces a very different, overly sugary syrup rather than an authentic, velvety porridge. Starting from scratch with dry adzuki beans gives you full control over the texture and sweetness level.

Why are my rice cake balls falling apart in the porridge?

Rice cake balls break apart if the dough was mixed with cold water instead of hot water, or if the dough was too wet when shaped. Hot water scalds the sweet rice starch, binding the dough firmly together so it holds its round shape during boiling.
