To make meat patty, combine beef, green onion, pickled daikon, oyster sauce, soy sauce, sesame oil, sugar, and white pepper in a bowl; mix well. Add stock and mix mixture by hand until it is smooth. Set aside
Wash and drain rice. Place rice and 1 1/2 cups water in a 2-quart clay pot or saucepan. Bring to a boil (over medium heat if using clay pot); decrease heat to very low, cover, and simmer until some water evaporates, 7 to 8 minutes
Spread the meat mixture on to of the rice into 6 to 7 inches in diameter. Press the center of the meat mixture with the back of your spoon to make and indentation enough to accomodate one egg. Cover and continue to cook until rice is tender and beef is barely pink in center, 10 minutes
Crack an egg into the indentation. To have a runny egg yolk, turn off heat and let stand for 10 minutes before serving. If you want it cooked all the way, crack an egg into the indentation and continue to steam it for another 5 minutes, turn off the heat
Notes
NOTE: At first I wanted a bright yellow egg yolk showing on the photo, but it was impossible to do so when I steamed the egg. If you want to make the yolk stands out, you need to separately pan-fried the egg :) and then place it on top of the beef patty. I should have done so before I took the photo shoot ;b
