Nokdu-muk is a yummy Korean food made from ground mung beans. Mung beans are like little seeds that grow in the ground and when they're ground up, they make a very soft and smooth texture. Think of it like when you mix flour and water together to make a paste.
To make nokdu-muk, first the mung beans are soaked in water overnight to make them soft. Then, they're ground up and mixed with water to make a very thin batter. This batter is then cooked over low heat and stirred constantly until it thickens and looks like a soft jelly. It kind of looks like Jello but it's not as wiggly!
Once the nokdu-muk is fully cooked, it's spread out into a shallow dish or on a flat surface to cool and solidify. After it's cooled, it can be cut into small squares or circles and eaten as a snack or added to other dishes for a soft and smooth texture.
Overall, nokdu-muk is a yummy and interesting food from Korea that's made from ground mung beans. It's very soft and smooth, kind of like Jello without the wiggles, and can be eaten as a snack or added to other dishes for a fun texture.
