Connie’s notes

What fish is good for this dish? Any firm fleshy fish. Tilapia is especially good. Skin-on, preferably, because the skin turns crisp like crackling during frying and that adds another layer of texture to this alreay texture-rich dish.
For the sauteeing part, although garlic and ginger are indispensable, the scallions may be replaced by thinly sliced shallots.
If you prefer more vegetables in the dish, thinly sliced carrot and sweet peas may be added.

Ingredients

Fish

  • 500 grams tilapia filllets (1.1 pounds) or fillets from other firm fleshy fish
  • 1 teaspoon herb salt or substitute ¾ teaspoon salt and ¼ teaspoon pepper

  • 1 bell pepper cored, deseeded and diced
  • 2 to 3 stalks scallions (white and light green portions only) thinly sliced
  • ¾ cup fresh pineapple chunks

Sweet sour sauce

  • ⅓ cup white sugar
  • ¼ cup rice vinegar
  • 2 pinches salt
  • 2 tablespoons plum sauce (available in Asian groceries)
  • 1 tablespoon tomato paste
