Teochew steamed fish is easy to make at home and the ingredients are relatively easy to get.
Sprinkle salt and white pepper on both sides of the fish fillet and set in a deep dish.
Arrange the tomato wedges, sour plum and tofu around the fish, and place the ginger slices on top.
In a small bowl, mix all the ingredients for the sauce and set aside.
In a sauce pan, heat up the cooking oil and add in the chopped garlic. Stir-fry until aromatic but not burnt.
Then add the pork, and stir-fry until half-cooked.
Lastly, add in the preserved mustard slices and continue to stir-fry for 1 minute.
Pour the sauce into the pan, let it come to a boil and turn off the heat.
Scatter the pork and preserved mustard on top and around the fish.
Pour the gravy over the fish and then steam the dish for 6 minutes or until the meat is thoroughly cooked.
Garnish and serve with steamed rice.
