Begin by combining ground pork, minced shrimp, chopped water chestnuts, carrots, and green onions in a large bowl. Add five-spice powder, salt, and pepper. Mix well. In a separate small bowl, stir cornstarch and water until smooth, then add this mixture to the pork mixture. Stir everything until fully combined.
Take a small portion of the mixture and fry it to test the seasoning. Adjust salt and spices to your taste if needed.
Prepare your bean curd sheets by trimming any hard edges and cutting them to fit your steamer size. Run each sheet under warm water to moisten, then gently squeeze out excess water to make them pliable.
Place a moistened bean curd sheet on a clean, flat surface. Spoon about one-third of the pork mixture across the bottom length of the sheet, leaving about 1 inch of space on the sides. Roll the sheet tightly around the filling to form a log about 2 inches thick. Moisten the end with water to seal, then twist the edges to lock in the filling. Repeat with remaining sheets and filling.
Arrange the rolls in your steamer, leaving space between each one. Steam for 15-20 minutes until the center reaches 145°F (63°C). Remove carefully and let cool completely. For best results, refrigerate until fully chilled.
Heat oil in a deep pan to 350°F (175°C). Carefully place the cooled rolls in the oil and fry in batches, turning occasionally, until golden brown and crispy on all sides. Keep the oil temperature steady between 330-355°F (165-180°C).
Remove from oil and let rest on paper towels for 5 minutes before slicing diagonally into serving portions.
For the dipping sauce, combine water, soy sauce, brown sugar, minced garlic, chopped shallots, chili pepper, flour, cornstarch, salt, and pepper in a saucepan. Whisk until smooth with no lumps. Cook over medium heat, stirring constantly, until the sauce thickens, about 3-5 minutes. Let cool before serving with your kikiam.
Serve hot with your choice of dipping sauce. Leftover kikiam can be stored in an airtight container in the refrigerator for up to 3 days or frozen for up to 3 months.
