Make the marinade by mixing together the sugar, salt, soy sauce and cornflour slurry. Mix in the pork, let marinate for 15 minutes.
Bring a large saucepan of water to the boil. Add the cauliflower and cook for 3 minutes or until tender. Drain and cool under a running cold tap. Set aside.
Heat a large frying pan with 1 tablespoon oil over high heat. Stir-fry the pork until it is cooked through, about 3-5 minutes. Stir in the shrimp and stir-fry until fragrant, 2-3 minutes. Stir in cauliflower florets.
Add 250ml water and bring it to the boil. Cover the pan with a lid and simmer for 10 minutes. Add some salt to taste and serve hot.
Dried shrimp can be purchased in Chinese/Oriental speciality stores or online.
