Mung Bean and Sea weed Drink

Mung bean and seaweed drink is a gentle Cambodian sweet soup that sits somewhere between a dessert and a cooling beverage. It is soft, lightly sweet, and surprisingly refreshing over ice.
The ingredients are simple: dried mung beans, a piece of pandan leaf, and dried seaweed simmered in water until everything turns tender. Sugar and a pinch of salt round out the flavor. Served warm, it feels like a comforting dessert. Poured over ice, it becomes a light drink for a hot afternoon.
What You Need
This recipe uses dried mung beans that have been soaked, dried seaweed, fresh or frozen pandan leaf, and two kinds of sugar. The full amounts are listed in the recipe card below.
Pandan leaf gives the soup a soft, grassy aroma. If you are new to pandan, look for frozen leaves in Asian grocery stores. The leaves are long, green, and fragrant even before they hit the pot.

How to Make Mung Bean and Seaweed Drink
Step 1: Prepare the Mung Beans and Seaweed
Put ½ cup of dried mung beans in a bowl and cover them with water. Let them soak for 4 hours. After soaking, pour the beans into a colander, rinse them under cold water, and let them drain.
While the beans soak, place ½ cup of dried seaweed in a separate bowl of cold water. Soak the seaweed until it softens, then rinse and drain it.
Step 2: Simmer the Mung Beans with Pandan
Put the drained mung beans into a large pot. Add 1 fresh or frozen pandan leaf and 9 cups of water.
Bring the pot to a boil, then lower the heat. Cook until the mung beans are tender. Stir occasionally so the beans cook evenly.
Step 3: Add the Seaweed, Sugar, and Salt
Add the drained seaweed to the pot. Add 1 cup of sugar, 1 cup of palm sugar or light brown sugar, and ½ teaspoon of salt.
Stir until the sugars dissolve completely. Continue cooking until the liquid comes back to a gentle bubble.
Step 4: Cool and Serve
Turn off the heat. Let the drink cool for a few minutes before serving.
Serve it warm in small bowls or glasses. For a cold drink, add ice cubes to each glass before pouring.
Cooking Tips
Soaking the mung beans for the full 4 hours helps them cook more evenly. If you are short on time, you can soak them longer in cold water, but do not skip the soaking step.
Taste the drink after the sugar dissolves. If you prefer it less sweet, start with a little less sugar and add more only after tasting. The recipe uses two types of sugar, and palm sugar brings a deeper, slightly caramel-like sweetness.
How to Serve
Serve this drink warm as a dessert soup, especially on a cooler evening. For a refreshing drink, fill a glass with ice cubes and ladle the sweet soup over the ice. The cold version is popular in Cambodia on hot days.
You can also serve it in small bowls with a spoon, the way many Cambodian sweet soups are enjoyed.
