Rinse and soak dried scallops in a small bowl of water until soften, about 30 minutes.
In a medium sized bowl, add minced pork, ¼ teaspoon pepper and soy sauce. Mix well and set aside to marinate.
Combine vegetable oil, sesame oil, and minced garlic in a microwave safe bowl. Microwave on high for 1½ minutes. Set aside.
In a large pot, rinse and drain rice until water runs clear, about 3 to 4 times. Add 10 cups (2.4 liters) of water and soaked scallops to the rice.
Set it on the stove and let water come to a boil. When water starts to boil, tilt the lid, reduce heat and let it simmer for about 15 minutes.
Add minced pork. Stir so that minced pork will break into small chunks.
Add salt and remaining ½ teaspoon ground pepper and continue to simmer for another 15 minutes. If porridge gets too thick, add ½ cup (120ml) water. Stir to mix.
To serve, ladle porridge into bowls. Garnish with garlic oil, green onions, ginger and yu char kway.
