Prepare the ingredients. Peel and slice the daikon and carrot. Finely chop the onion, mince the garlic, and roughly chop the coriander root. Set everything aside and keep it ready.
Bring water to a boil in a soup pot over medium heat. Add the chopped onion, garlic, and coriander root. Let it simmer for 1–2 minutes to release the aroma.
Add the sliced daikon and carrots to the pot. Simmer until the vegetables begin to soften slightly.
Add the bouillon cube, salt, and white pepper powder. Reduce the heat to low-medium and let the soup simmer while preparing the meatballs.
Season the ground pork with a pinch of salt and pepper. Mix well and roll into small meatballs.
Gently drop the raw pork meatballs into the soup. Let them simmer until fully cooked and floating.
Once the vegetables are tender and the broth is flavorful, turn off the heat. Serve warm, garnished with chopped green onions or cilantro if desired.
