Preheat the oven to 350°. Combine crab, mascarpone, cream cheese, scallion, Worcestershire, and garlic powder. Mix well. Put in a small casserole dish an bake fo 15 minutes.
While the dip is baking, fry the wontons. Using a sharp knife cut the wonton wrappers in half. Heat oil into a heavy-bottomed skillet to 350°, or until a wooden spoon dipped in the oil gets covered with bubbles immediately. Turn the heat down just a little to maintain the temperature.
Working in batches, fry the wontons a few at a time. As soon as the edges begin to brown, flip them over. They will brown very quickly, and they will brown even faster on the second side. Drain on paper towels. Sprinkle with salt.
To serve, spoon sweet chili sauce on top of the dip. Serve at room temperature with fried wontons.
