Ingredients for black bean milk korean
Nine simple ingredients craft this velvety Korean black bean milk with authentic depth and modern versatility.
| Ingredient | Amount | Notes |
|---|---|---|
| Black Soybeans 🌱 | 1 cup | Dried, organic preferred |
| Sweet Rice Flour 🌾 | ½ cup | Glutinous rice flour |
| Granulated Sugar 🍚 | ¼ cup | Adjust to taste |
| Water 💧 | 4 cups | Filtered preferred |
| Cinnamon Sticks 🌿 | 2 whole | For infusion |
| Fresh Ginger Root 🧡 | 1 inch | Peeled, sliced thin |
| Vanilla Extract 🌸 | 1 tsp | Optional, pure extract |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Ice Cubes ❄️ | 1 cup | For serving |
The black soybeans are the heart of this drink—Korean markets or specialty Asian grocery stores carry the best quality, often labeled as 'kongnamul' or 'black mung beans'. Look for organic varieties when possible, as they tend to have a richer, nuttier flavor profile. Sweet rice flour is non-negotiable; Bob's Red Mill or Trader Joe's carry excellent options. The cinnamon sticks should be whole and aromatic—McCormick or Penzeys offer high-quality varieties. Ginger needs to be fresh; frozen works in a pinch but lacks the same brightness.
No sweet rice flour? Arrowroot powder at double the amount creates a similar texture, though with slightly less body. Substitute maple syrup for sugar if you prefer a less refined sweetener—equal parts by volume. Vanilla extract can be omitted entirely, but if you use imitation, add 0.5 tsp more to compensate for lower potency. The lemon juice isn't just for acidity; it brightens the earthy bean flavors. For a dairy-free froth, blend the finished milk with 1 tsp coconut cream before serving. Store-bought black bean milk lacks the silky texture achieved through traditional soaking and straining—this method truly makes the difference.
Soak the beans overnight in plenty of cold water to reduce bitterness. The finished milk keeps in the fridge for 5-7 days when stored in a sealed glass jar. For a restaurant-quality presentation, serve over crushed ice with a cinnamon stick garnish. Freeze in ice cube trays for quick smoothie additions—thaw and blend directly into your favorite recipes. The flour mixture should be smooth; strain through a fine-mesh sieve for the silkiest results.

Step-by-step instructions for black bean milk Korean recipe
This silky-smooth Korean-style black bean milk requires precise technique for perfect texture and flavor.
Soak and Cook the Black Soybeans
Rinse the 1 cup black soybeans thoroughly under cold water to remove any debris. Place them in a bowl and cover with plenty of fresh cold water—at least 3 inches above the beans. Let them soak for 8 to 12 hours at room temperature, or overnight in the refrigerator. This extended soaking ensures the beans soften completely and blend smoothly.
Drain and rinse the soaked beans again before transferring them to a pot. Add the 4 cups water and bring to a boil over medium-high heat. Once boiling, reduce heat to medium-low and simmer for 45 to 60 minutes, stirring occasionally, until the beans are fork-tender and the liquid has reduced by about one-third. You'll know they're ready when they mash easily between your fingers with minimal resistance. The cooking liquid will form the base of your milk—don't drain it yet.
Blend and Strain the Bean Mixture
Transfer the cooked beans and their cooking liquid to a high-powered blender. Add the 0.5 cup sweet rice flour, 0.25 cup granulated sugar, 0.25 tsp salt, and 1 tbsp lemon juice. Blend on high speed for 1 to 2 minutes until completely smooth, scraping down the sides as needed. The mixture should have a velvety, homogeneous consistency with no visible bean particles.
Strain the blended mixture through a fine-mesh sieve or cheesecloth lined with a clean kitchen towel into a large bowl. Apply gentle pressure with a wooden spoon to extract all the liquid. Discard the solids. This step is crucial for achieving that signature silky texture—any remaining fiber will make the final product gritty. The strained liquid should measure about 3 cups, with a rich, chocolatey aroma and deep black color.
Infuse with Aromatics and Flavor
In a separate saucepan, combine the strained black bean liquid with the 2 whole cinnamon sticks and 1 inch peeled, thinly sliced fresh ginger root. Heat over medium-low heat until just simmering—you should see gentle bubbles forming around the edges but not a full rolling boil. Simmer uncovered for 10 to 12 minutes, allowing the cinnamon and ginger to infuse their flavors into the liquid.
Remove from heat and let steep for an additional 5 minutes. Strain again through a fine-mesh sieve to remove the cinnamon sticks and ginger pieces. Return the liquid to the saucepan and stir in the 1 tsp vanilla extract. Taste and adjust sweetness if needed—you can add more granulated sugar at this stage if desired. The finished infusion should have warm, spiced notes with a subtle citrus brightness from the lemon juice.
Chill and Serve
Transfer the infused black bean milk to a clean glass container and refrigerate for at least 2 hours, or until completely chilled. This cooling step allows all the flavors to meld together fully. For serving, pour the chilled black bean milk into glasses filled with 1 cup ice cubes. The contrast between the warm spices and cold milk creates an incredibly refreshing beverage.
The final product should have a luxurious, creamy texture with a rich chocolatey depth and aromatic cinnamon-ginger notes. Each sip should reveal layers of complexity—sweet, spiced, and subtly tangy. For an extra touch, garnish with a sprinkle of ground cinnamon or a cinnamon stick stirrer. This beverage holds well in the refrigerator for up to 5 days, making it perfect for meal prep or enjoying throughout the week.
Pro Tips For Making Black Bean Milk Korean
- SOAK BEANS OVERNIGHT: I learned this the hard way—rushing the soak leaves gritty, unappetizing milk. Use 4 cups water per 1 cup dried black soybeans, soak 8+ hours (or overnight), then drain and rinse thoroughly. The extra time pays off with silky texture, not chalky bits.
- WHISK HOT LIQUID HARD: After burning three batches, I finally figured out: the sweet rice flour needs to be whipped into the boiling water, not warm liquid. Use a hand mixer for 2-3 minutes until the paste is glossy and fully dissolved—this prevents clumping and gives that signature velvety body.
- SWEETEN GRADUALLY: Dumping all the sugar at once makes the milk split or turn grainy. Start with half the sugar while heating, then whisk in the rest after the flour is dissolved. Taste as you go—Korean black bean milk balances sweetness with earthy depth, so err on the lighter side first.
- STRAIN TWICE: Sounds weird, but it works: after simmering, strain through a fine-mesh sieve twice—first to catch fiber, then a cheesecloth-lined strainer for ultra-smooth milk. The second pass removes the last of the starchy residue that dulls the flavor. (Yes, it’s extra effort, but the result is restaurant-quality.)
Regional styles of this black bean milk korean
Traditional Korean Style
In Korea, this drink is known as kongnamul cha and has been enjoyed for centuries as both a refreshing beverage and medicinal tonic. The traditional method emphasizes simplicity: soaking black soybeans overnight, simmering them gently, and straining through cheesecloth for that signature silky texture.
I've found that using organic Korean black soybeans from specialty markets makes all the difference—they develop a deeper, nuttier flavor. Serve it chilled with a cinnamon stick stirrer for an authentic touch. 🌿
Modern Seoul Twist
Seoul's trendy cafés have put their own spin on this classic by blending it into black bean milk lattes with oat milk and espresso. For a café-style version, whisk ½ cup chilled black bean milk with ½ cup steamed oat milk and a shot of espresso.
Top with cinnamon whipped cream made by blending chilled coconut cream with 1 tsp powdered sugar and ½ tsp cinnamon. The contrast of hot and cold creates a sophisticated drink that's perfect for brunch. 💛
Jeju Island Variation
On Jeju Island, they incorporate local ingredients like Jeju honey and green tea powder for a unique twist. Replace the granulated sugar with 2 tbsp Jeju honey and add 1 tsp matcha powder during the infusion step.
The result is a floral, slightly bitter profile that balances beautifully with the earthy beans. This version works wonderfully as a dessert accompaniment or paired with bingsu (Korean shaved ice dessert). ✨
Winter Spiced Adaptation
For colder months, Koreans often enhance this drink with warming spices. After the initial infusion, add ½ tsp ground star anise and ¼ tsp black pepper during the simmering phase.
The star anise adds a licorice-like depth while black pepper provides a subtle kick. This winter version pairs perfectly with mandu (Korean dumplings) or tteokbokki for a cozy meal. 🔥
Dessert-Inspired Fusion
Modern Korean patisseries have transformed this drink into dessert form by creating black bean milk panna cotta. Mix 1 cup chilled black bean milk with 1 cup coconut cream and 3 tbsp agar-agar powder.
Heat gently until dissolved, then pour into ramekins and chill for 4 hours**. Top with caramelized bananas and toasted sesame seeds for a luxurious dessert that's both elegant and comforting. 💫

Frequently asked questions
Why does the recipe call for soaking black soybeans overnight?
Overnight soaking is essential to reduce bitterness and soften the beans completely. This step ensures they blend smoothly into a velvety texture. The longer soak also helps extract more flavor compounds, creating that rich, chocolatey depth characteristic of authentic Korean black bean milk.
Can I make this drink without sweet rice flour?
Yes! Use arrowroot powder at double the amount for a similar texture, though it may be slightly less creamy. For a more traditional approach, try cornstarch (½ tsp) mixed with cold water to make a slurry. Both alternatives work well but won't match the authentic mouthfeel of sweet rice flour.
How do I fix gritty texture in my black bean milk?
Grittiness usually means unblended bean particles. Strain the mixture again through a fine-mesh sieve or cheesecloth, pressing gently with a spoon. For extra smoothness, blend the strained liquid for 30 seconds after the first straining. The key is patience—take your time pressing to extract all liquid from the solids.
Is this drink naturally vegan?
This recipe contains only plant-based ingredients—black beans, sweet rice flour, and natural sweeteners. The vanilla extract and cinnamon are also vegan-friendly. For added creaminess, use coconut cream instead of dairy-based whipped cream when serving.
Can I make this ahead of time for gatherings?
Yes, it actually improves with time! Prepare the drink 1-2 days in advance and store in an airtight container in the fridge. The flavors meld beautifully, and it stays fresh for 5-7 days. For serving, simply chill and pour over ice—no reheating needed. Perfect for meal prep or entertaining!
