Heat a fry pan with a teaspoon of cooking oil at medium-low heat. Place about 8 dumplings in and cover the lid. Cook for about 5 minutes. Then open lid and flip the dumplings and cook for another 5 minutes or so. You may need to adjust the timing as needed by checking the seared surface, it should be golden brown. And if you’re unsure if the meat is cooked through, add one tablespoon of water to the pan, cover immediately and allow steam to cook them through for 2 minutes.
