1. Shell and devein the shrimp, removing and discarding the heads and legs, if necessary, then rinse and shake dry. Put them in a bowl, add the marinade ingredients, and mix well; set aside

2. Trim the chives, discarding any tougher or wilted leaves (they should be pert and fresh) and cut into 1 ¼-inch pieces.

3. Heat the oil in a wok over a high flame until it reaches 300°F. Discard any excess egg white from the shrimp, then add them to the wok and fry briefly until pinkish but not fully cooked. Remove with a slotted spoon and set aside.

4. Drain off all but 3 tablespoons of the oil. Add the garlic and chopped salted chiles and stir-fry briefly until fragrant. Add the shrimp, stirring well, followed by the vinegar.

5. When all is sizzling and delicious, add the chives and fresh chili and stir-fry until they are barely cooked. Season with salt to taste, then remove from the heat, stir in the sesame oil, and serve.

Variation:

A similar recipe uses finely chopped garlic stems instead of Chinese chives; the method is the same except you stir-fry the garlic stems with the ginger and chopped salted chiles until fragrant, before adding the shrimp.
