Let the cream cheese come to room temperature, then beat it with the soy sauce, onions, garlic and a pinch each of salt and black pepper. Mix in the crabmeat.
Put a teaspoon of crab rangoon mixture in the center of each wonton wrapper, then spread it out a bit but keeping it away from the edges.
Wet the 4 points of the wonton wrapper with water and bring them all towards the center (like in the photo) to seal them.
Heat the oil in a pot to 350 degrees F (180 degrees C) and fry the wontons in batches for 3 minutes or until they are light golden brown. Drain them on paper towels and serve hot, garnished with fresh dill.
