Place pork in a large bowl, and add oyster sauce, soy sauce, sesame oil, sugar, sea salt, and ground black pepper. Stir together and set aside to marinate while you prepare the eggs.
8 oz ground pork, 2 tsp oyster sauce, 2 tsp soy sauce, 1 tsp sesame oil, 1/2 tsp sugar, 1/2 tsp sea salt, 1/8 tsp ground black pepper
Combine all ingredients for the steamed eggs in a bowl, and whisk together well until smooth.
4 large eggs, 1½ cup water, 1/2 tsp sea salt
Strain the egg mixture through a fine-mesh strainer into a heat-safe shallow bowl that can fit inside a large pot. Spoon out any bubbles that form on the top. Cover the bowl with a plastic wrap and pierce a few holes to allow the steam to escape.
Bring 1 inch of water to a boil in a large pot then place a steamer rack (like this one) inside. Place the bowl on the basket, making sure the water doesn't touch the bowl. Cover, bring the heat down to medium, and steam for 10-11 minutes while you cook the pork. Heat avocado oil in a large skillet over medium high heat. Add the marinated pork and stir cooking until the meat is no longer brown, about 4-5 minutes.
1 tbsp avocado oil
Add garlic and stir for 1 minute until fragrant.
4 garlic cloves
Whisk together water and arrowroot starch and pour into the skillet. Cook until the sauce is thickened - about 1-2 minutes. You can taste to adjust seasoning at this point.
1/2 cup water, 2 tsp arrowroot starch
Turn off heat, and stir in green onions.
2 green onion
Once the eggs are cooked, remove from the steamer. If you wish, use a knife to make cuts into the eggs, so the pork mixture can seep in.
Top with the pork mixture, sprinkle more green onions, and serve warm.
