Blend all the Lemon paste ingredients in a blender until smooth, approximately 2 to 3 minutes.
Combine the lemongrass paste in a bowl with the shredded coconut, sugar and salt, mixing well. Add the pieces of pork and stir to coat thoroughly with the paste. Let marinate for at least an hour at room temperature or as long as overnight in the refrigerator.
Prepare a charcoal grill according to manufacturer's instructions or preheat the broiler, positioning a rack about 4 inches from the heat. Dividing the pieces of meat evenly, thread the meat onto wooden or metal skewers. Grill for 3 to 4 minutes per side, until the pork is nicely browned on the outside and just cooked through - but not dry - on the inside. Serve immediately.
