In a large mixing bowl, combine ground pork through sesame oil and 2 egg whites. Mix well using your hands. In a small bowl, combine remaining egg white and a splash of water to use as the binder on your won ton wrapper.
Place on wrapper on a flat surface and using your fingers and the egg white mixture, moisten the edges. Place a ball of 1-2 tablespoons of pork mixture in the center. Fold wrapper in half and secure one end with your thumb. Gently pinch one small fold and move your thumb over it, pressing lightly to deal. Continue with seven more folds (or however many you can get) to secure it closed. Repeat with remaining wrappers.
In a large skillet, heat 1 tablespoon vegetable oil over medium-high heat. Add a few dumplings, making sure to not crowd the pot and gently fry on all sides until nice and brown, approximately 3-4 minutes.
Add a small amount of water, just a splash, and cover to finish cooking by steaming, approximately 2-3 minutes. Remove with a slotted spoon to a baking sheet. You can place them in a warm oven to stay hot until all batches are complete. Add additional vegetable oil as needed to prevent dumplings from sticking.
After you are done pan frying and steaming all of your dumplings, add all of the dipping sauce ingredients to the same frying pan without rinsing it out. Stir until it comes to a low simmer, then remove and serve immediately with dumplings.
