Take out a separate pot - one with a matching lid. Now add-in 1L of water (~4.5 cups). Next, add in a piece of Korean Radish (150~200g), ½ an Onion, 4 Garlic Cloves, 1 forearm-sized piece of Spring Onion Stalk, 3-4 Bay Leaves and Whole Black Pepper (½ teaspoon!)
Turn on high heat and bring pot up to a rolling boil.
Once the pot is at a rolling boil, add the brisket pieces into the pot. Now place the lid on.
Wait for the pot to come back up to a rolling boil. Once it does, reduce the heat to a LOW heat... and set a timer for 50 minutes.
15 minutes into the boil... remove the spring onion stalk from the pot and give it a quick stir. Let the pot continue to gently simmer away for the rest of the 35 minutes...
In the meanwhile, move to toppings & dipping sauce.
