Wrap Tofu (300 gram) with a piece of muslin cloth, then place a heavy object on top to squeeze out the moisture from the block, for about 30 minutes.
Place Ground Pork (100 gram), Peeled Prawn (60 gram) Egg (1) and tofu in the food processor together with the Corn Starch (2 tablespoon), Light Soy Sauce (1/2 tablespoon), Oyster Sauce (1/2 tablespoon), Chicken Powder (1 teaspoon), Salt (1/2 teaspoon), and Ground Black Pepper (1 dash). Blend tofu mixture coarsely and not too fine, then transfer to a bowl.
Add in Spring Onion (3 stalk) and Peeled Prawn (90 gram) with more pepper, mix well.
Place about 2 teaspoon of the tofu mixture in the middle of the Dumpling Wrappers (35) and moisten the edge with little water. Fold it up over, use your fingers to make a small pleat on one side of the wrapper until completely sealed like a crescent shape. Repeat the same until you use up the ingredients.
Add 2-3 tablespoons oil into heated pan, place in the guo tie and fry them at medium heat until the bottoms till crisp and golden brown, about 2-3 minutes.
Pour 1/4 cup of water from the sides of the pan. Cover with a lid and reduce to low heat. Cook guo tie for another 3-5 minutes or till fully cooked. You may add a little more water if it dries up quickly and before the guo tie are done cooking.
Serve guo tie immediately with dipping sauce. Enjoy!
