Take out a large pot. Put it on medium-high heat. Place in Toasted Sesame Oil (2 Tablespoons). Once the oil gets hot, place in the beef pieces (200 grams). Stir-fry until the beef loses most of its red color. Then add-in the Korean Radish pieces (3-4 cups). Stir-fry for 1-2 minutes or until the radish starts to sweat.
Then add in the 5 cups of Rice Water (or anchovy-kelp broth). Wait until it comes to a boil. Then use a soup ladle to skim the scum off the surface.
Now, let's season the soup. Add in Soy Sauce (2 Tablespoons) and Minced Garlic (1 Tablespoon). Place a lid-on. Reduce the heat to a medium-low. Let it gently boil for 10-15 minutes or until the radish turns very soft.
After 10-15 minutes, take a sip of the soup. (You can add a dash of water if its tastes salty.) Then add in Black Pepper (2-3 cracks). And add a handful of Spring Onions Slices.
Serve in a bowl - alongside a bowl of hot rice!
