1. Start by making the dumpling dough. Place the flour in a large bowl. Carefully pour in the boiling water while stirring with a fork or chopsticks until the dough starts to come together.
2. Once cool enough to handle, knead the dough on a lightly floured surface for about 5-7 minutes until smooth and elastic. Cover it with a damp cloth and let it rest for at least 30 minutes. This step is key for a tender wrapper.
3. While the dough rests, prepare the filling. In a medium bowl, combine the chopped shrimp, green onions, grated ginger, minced garlic, soy sauce, sesame oil, sugar, salt, and white pepper. If you like a bit of crunch, fold in the chopped water chestnuts.
4. Divide the rested dough into small, equal pieces—about 1-inch balls. Roll each ball out on a floured surface into a thin circle roughly 3 inches in diameter. Don’t worry about perfect circles; in my kitchen, these always end up a little wonky, and that’s part of the charm.
5. Place about a tablespoon of filling in the center of each wrapper. Fold the dough over to create a half-moon shape and pinch the edges to seal. You can pleat the edges if you want to get fancy, but a simple pinch works just fine.
6. To cook, bring a large pot of water to a boil. Drop the dumplings in batches, stirring gently to prevent sticking. When they float to the surface, cook an additional 2-3 minutes to ensure the shrimp is fully cooked. Remove with a slotted spoon.
7. Alternatively, you can steam the dumplings by placing them in a bamboo steamer lined with parchment paper and steaming over boiling water for about 8 minutes.
8. Serve hot with a dipping sauce made from soy sauce, rice vinegar, and a touch of chili oil if you like a kick.

When I first made these, my toddler insisted on helping with the filling, which meant a fair amount of shrimp ended up on the floor. But the joy of cooking together and the reward of those first bites made the mess totally worth it!
