Charm Juk Korean Porridge: A Creamy Sesame Recipe at Home

Charm juk is a Korean rice porridge made here with toasted black sesame seeds, short-grain rice, and water for a silky, nutty bowl. It is a simple, comforting dish that can be served savory or gently sweet, and the rice thickens naturally as it cooks. This recipe is a black-sesame version of chamkkae-juk, or sesame juk; ingredients and texture vary between cooks and families.

Ingredients

½ cup (100 g) short-grain white rice, such as Korean or Japanese-style rice
½ cup (70 g) hulled black sesame seeds
5 cups (1.2 L) water, divided
¾ teaspoon (4.5 g) fine salt, plus more to taste
1 teaspoon (5 ml) toasted sesame oil, optional, for a savory finish
1 teaspoon (3 g) extra toasted sesame seeds, optional, for garnish
1 tablespoon (3 g) thinly sliced scallion, optional, for a savory garnish
1–2 teaspoons (7–14 g) honey or sugar per bowl, optional, for a sweet finish

Instructions

Rinse and soak the rice. Put the rice in a bowl and cover it with cool water. Swirl it with your fingers, pour off the cloudy water, and repeat two or three times, until the water is less cloudy. Cover the rice with fresh water and leave it to soak for 1 hour. This gives the grains a head start softening, helping them cook evenly and blend into a smooth porridge. Drain well before blending.
Toast the sesame seeds. While the rice soaks, warm a dry skillet over medium-low heat. Add the black sesame seeds and stir or shake the pan for 3–4 minutes, until they smell nutty. They can scorch quickly, so keep them moving and take the pan off the heat as soon as they are fragrant. Transfer the seeds to a plate to cool; leaving them in the hot skillet can darken them further and make them bitter.
Blend the rice and sesame separately. Put the drained rice in a blender with 1 cup (240 ml) of the measured water. Pulse until the grains are broken into small pieces but not completely puréed; a little texture makes a pleasant, traditional-style porridge. Transfer the rice mixture to a bowl. Add the cooled sesame seeds and another 1 cup (240 ml) of water to the blender, then blend until the seeds are as finely ground as possible. If your blender needs help moving the seeds, pause to scrape down the sides rather than adding unmeasured liquid.
Start the rice porridge. Pour the rice mixture into a heavy-bottomed saucepan and stir in the remaining 3 cups (720 ml) of water. Set the pan over medium heat and stir frequently as the liquid warms, scraping the bottom and corners. When it begins to simmer, reduce the heat to low. Cook gently for about 26 minutes, stirring every minute or two, and more often as it thickens. A steady gentle simmer is better than a vigorous boil, which can make the porridge spit and stick.
Add the sesame mixture. Stir the blended sesame mixture well, since ground seeds can settle, then pour it into the saucepan. Add the salt and keep the porridge at a gentle simmer for 5 minutes, stirring continuously so the sesame does not catch on the bottom. The porridge should look glossy and creamy, with no firm rice grains. If it becomes thicker than you like, stir in hot water a few tablespoons at a time. If it is still loose, simmer for another minute or two, stirring.
Season and serve. Taste and add more salt for a savory bowl. For a mellow, rounded finish, stir in the optional sesame oil. Spoon the juk into warm bowls and add toasted sesame seeds or scallion if desired. For a sweet bowl, leave out the scallion and sesame oil, then sweeten each serving with honey or sugar to taste. The porridge thickens as it stands, so serve it soon after cooking or loosen it with a splash of hot water.

Tips

Choose the right sesame. Hulled black sesame seeds blend into a relatively smooth porridge and give it a deep, nutty flavor. Whole, unhulled seeds can taste more assertive and may leave a slightly gritty texture. If black sesame is hard to find, use hulled white sesame seeds in the same quantity; the porridge will be paler and its flavor milder, but the method stays the same.
Use short-grain rice for body. Korean short-grain rice becomes naturally creamy as its starch releases. Medium-grain rice is a workable substitute, though the porridge may be a little less cohesive. Long-grain rice can be used in a pinch, but it tends to give a looser, less silky result. Avoid adding extra rice without increasing the water and cooking time.
Control the heat and keep stirring. Once the rice mixture begins to simmer, lower the heat and stir regularly, reaching along the base of the pan. The starch settles as the porridge thickens, so a pot that is left unattended can scorch even when the surface looks calm. A heavy saucepan helps distribute heat more evenly.
Adjust thickness at the end. Juk can range from spoonable and loose to quite thick, and it continues to set as it cools. Add hot water gradually if it is too thick, tasting again for salt afterward. If the sesame flavor seems harsh, check that the seeds were toasted only until fragrant, not browned deeply.

Serving Suggestions

Serve charm juk hot as a light meal, breakfast, or one course in a Korean-style spread. For a savory bowl, finish with a few drops of toasted sesame oil, sliced scallion, and a small pinch of sesame seeds. The garnish should add aroma and contrast without covering the mild rice-and-sesame flavor. Salt levels can be adjusted at the table, which is useful when serving people who prefer different levels of seasoning.

For a sweet version, offer honey, sugar, or a little more sesame as optional toppings. Start with a small amount of sweetener; sesame has a rich flavor, and a lightly sweet bowl lets it come through. You can also serve the porridge alongside small portions of kimchi or other banchan for a savory meal. Keep strong, spicy sides separate so each person can decide how much contrast they want with the gentle porridge.

Serve the juk in prewarmed bowls if you want it to stay loose for longer. A small bowl is satisfying as part of a larger meal, while a larger serving can stand on its own. Put any extra hot water on the table so diners can thin their portions as they eat. The porridge naturally thickens during serving, and adding water to each bowl is often easier than trying to keep the whole pot at exactly the same consistency.

Variations

Use white sesame. Replace the black sesame with ½ cup (70 g) hulled white sesame seeds. Toast them gently using the same method and blend with water. White sesame makes a lighter-colored, somewhat milder porridge; it is a useful option if black sesame is unavailable or if you prefer a subtler sesame flavor.

Make it extra smooth. Blend the rice mixture longer, until it is nearly smooth, and stir more frequently during cooking. The result will be silkier and less textured. A powerful blender can make the sesame mixture especially fine, but a little graininess is normal when using a standard home blender. Avoid blending hot porridge in a sealed blender, as hot liquids can build pressure; blend the ingredients before cooking instead.

Add a simple topping. Keep the base recipe as written and add a small amount of finely chopped scallion, toasted sesame, or a drizzle of sesame oil to individual savory bowls. For a sweeter bowl, choose honey or sugar instead. Adding toppings at the table lets one batch suit different preferences without changing the cooking process.

Make the porridge richer. For a fuller mouthfeel, replace up to 1 cup (240 ml) of the water with unsweetened, unflavored soy milk. Add it with the sesame mixture and keep the heat low; it can scorch more readily than water. This changes the flavor and is not necessary for a creamy result, since the rice starch already thickens the porridge.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in a covered, shallow container. Charm juk keeps for 3–4 days in the refrigerator. It will become quite firm as the rice absorbs liquid, which is normal. For easier reheating, portion it into individual containers before chilling. Do not leave cooked rice porridge at room temperature for an extended period.

Reheat a portion on the stove over low heat with a splash of water, stirring until it loosens and heats evenly. You can also use a microwave-safe bowl: cover loosely, heat in short intervals, and stir between intervals. Leftovers should reach 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers; check with a food thermometer, stirring first so the temperature is even. Add more hot water if needed, then adjust the salt. Freezing is possible for up to about 2 months, though the texture may become less smooth; thaw overnight in the refrigerator and reheat with water.

Frequently Asked Questions

Is charm juk the same as black sesame porridge?

Charm juk is a romanized way people may refer to Korean sesame juk, often written as chamkkae-juk. Sesame porridge can be made with black or white sesame, so the name does not always mean the seeds must be black. This version uses black sesame for a darker color and a pronounced toasted flavor.

Do I have to soak the rice?

Soaking for 1 hour helps the rice soften and makes the cooking more predictable, especially when the grains are blended before simmering. If you skip soaking, the rice may take longer to cook and can remain firmer in the finished bowl. If time is short, soak it in warm—not hot—water while you prepare the sesame, but check the grains for tenderness before serving.

Can I make this without a blender?

A blender gives the smoothest sesame mixture and breaks the rice into small pieces, but you can still make the porridge without one. Finely grind the toasted sesame in a spice grinder or mortar and pestle, then cook the soaked rice whole in the water until very soft, stirring and gently mashing it as it cooks. Stir in the ground sesame near the end. The result will have a more textured consistency.

Why did my porridge become too thick?

Rice continues absorbing liquid as the porridge cools, and the mixture also thickens as it stands in the bowl. Stir in hot water a little at a time until it reaches the consistency you want. If you are reheating chilled juk, expect to need more water than you would for a freshly cooked serving. Taste afterward, since added water can dilute the seasoning.

Can I prepare charm juk ahead?

Yes. You can rinse and soak the rice, then refrigerate it covered for up to 8 hours before draining and cooking. You can also toast the sesame seeds ahead and store them in an airtight container at room temperature for several days. For the best texture, cook the porridge close to serving time, or refrigerate the finished dish promptly and reheat it with water.
