Preparation
Preheat oven to 400ºF.
In the bowl of a food processor fitted with a chopping blade, place ginger, garlic, lemon grass and scallions; pulse until finely chopped. Add shrimp, pork, oil and soy sauce; pulse to combine. Spoon mixture into a small bowl and mix well to combine.
Lightly coat a baking sheet with cooking spray. Place wonton wrappers on prepared baking sheet so they look like diamonds.
Fill a small bowl with water and using your finger or a small pastry brush, coat edges of wrappers with water. Spoon a heaping teaspoon of shrimp mixture onto middle of each wrapper; fold each wrap over filling to make a triangle and press to seal edges.
Coat tops of wontons with cooking spray and bake, flipping once, about 3 minutes per side. If wontons are not crispy enough, cook for 1 to 2 minutes more.
Meanwhile, while wontons are baking, in a small bowl, stir together preserves, water, lime juice and fish sauce. Serve wontons with dipping sauce on the side. Yields 4 wontons and about 1 tablespoon of sauce per serving.
