2. If you are adding the oysters, wash them in salted water, and drain.


3. Slice the green onion (and watercress if you are adding it) into 1 to 1-and-a-quarter inch (2.5-3cm) strips.


4. Make sure the garlic and ginger are finely chopped.


5. Mix the warm water and red pepper powder to make a paste.


6. Using your hands, mix the red pepper paste with the radish cubes.


7. Add the remaining ingredients to the red pepper and radish mixture. Mix well by hand.


8. Once well mixed, place into a small earthenware pot and let sit for a day in a cool spot. After a day taste the mixture to see if it has begun to ferment. Once it has started fermenting you can put it in the refrigerator. Allow it to ferment in the refrigerator for another few days (up to a week) before serving.
