In the small bowl, combine all ingredients of the sauce and set aside
Season the shrimps with salt and pepper. Leave for 15 minutes and wipe off the excess water.
Make pork filling. In a large bowl, mix the pork, spring onion, garlic, ginger, potato starch until fully incorporated. Mix the water, salt and pepper, then at last mix the sesame oil in.
Place 1 tsp of the pork filling and one shrimp in the center of the wonton wrapper. Using your finger, wet the edges of wonton wrapper with water. Fold wonton and seal the edges. Repeat until 30 wonton wrappers are filled.
In a large pot, bring water to a boil, and then turn down the heat to low. Cook ten wontons until they float to the surface for 3-4 minutes. Remove with a scoop spoon, and transfer to a serving plate. Repeat until all wontons are cooked.
Pour the sauce over the wonton and garnish with coriander leaves. Enjoy!
