– In a saucepan, add quail eggs and fill the water enough to cover the eggs. Bring it to a boil, and simmer for 3 minutes. Turn off the heat, drain the water, and transfer the eggs to a bowl filled with cold water immediately. Let the eggs soak in the cold water for 10 minutes or until they cool off completely.
– Meanwhile, prepare the marinade sauce by combining soy sauce, water, sugar, garlic, green onion, and chili pepper in a mason jar. Stir well and set aside.
