  • 12 ounces cod fillet 340g, rinsed clean, pat dry and cut into 1-inch cubes
  • 3 cups canola oil for frying
  • ¾ cup all-purpose flour
  • ¼ teaspoon baking powder
  • 1 tablespoon cornstarch
  • ½ teaspoon salt
  • teaspoon turmeric powder
  • teaspoon white pepper
  • ¼ teaspoon sesame oil
  • cup cold seltzer or club soda


  • Make sure your fish fillet is clean and pat dry to ensure your fried fish gets really crispy. Heat 3 cups of oil in a small pot (to conserve oil) to 380 degrees F. You can use a thermometer or check the temperature by putting a drop of batter into the oil. The batter should not turn brown right away. Instead, it should rise immediately to the surface and turn a very light golden brown.
  • To make the batter, mix together all the dry ingredients––the flour, baking powder, cornstarch, salt, turmeric, and white pepper. When you’re ready to fry, mix in the sesame oil and cold seltzer water until the batter is smooth.
  • Next, drop the fish fillets into the batter. Ensure they are evenly coated, but allow the excess to drip off (if there’s too much batter on the fish, you’ll end up with dough balls!). Carefully place the fish into the oil one piece at a time, ensuring that they don’t stick to each other. Fry in batches so that the fish pieces aren’t overcrowded, frying for 3-4 minutes or until golden brown.
  • Scoop the fried fish out and transfer to a cooling rack placed over a baking sheet to drain. Repeat until all the fish has been fried.
  • Next, put two teaspoons of the frying oil in a separate wok or skillet over high heat, and toss in the onions, and peppers. Stir-fry for 30 seconds, and then stir in the ketchup. Fry for another 20 seconds––frying the ketchup brings out the color and makes for a better depth of flavor in the sweet and sour sauce.
  • Mix in the pineapple, pineapple juice, red wine vinegar, water, salt, and sugar, and bring the liquid to a low simmer for 2 minutes. With the sweet and sour sauce still simmering, slowly stir in the cornstarch slurry until the sauce is thick enough to coat a spoon.
  • At this point, if the fried fish fillets have softened, you can refry them in the oil heated to 400F for 30 seconds in larger batches. The higher heat is needed because the oil will cool immediately after putting in a larger batch of fish in the oil.
  • Once the fish is ready, toss it into the wok, and fold into the sauce with 3 or 4 scooping motions until the pieces are lightly coated. Plate and serve immediately!


For an authentic Chinese dish, the fish should be deep-fried. You can also use pineapple or lychee halves as an alternative. After frying, simply coat the fish with the sauce and serve it. A delicious sweet and sour fried fish fillet will be ready in less than an hour. Besides, this recipe is suitable for lunch or dinner. It's good to add a little sugar.

Tips for Sweet and Sour Fish Fillet

Sweet and sour fish- How to cook the Malaysian Chinese way

Here are some of my top tips for making the best sweet and sour fish fillet at home:

  • Choose a sturdy white fish – I prefer a firm, white fish like tilapia or cod that won’t fall apart when battered and fried. Stay away from more delicate fish like sole or flounder.
  • Make the batter light – A batter made with flour, cornstarch, baking powder, and cold water fries up deliciously crispy and puffy. The baking powder is key for maximum crispness.
  • Fry in batches – Don’t crowd the pan when frying. Fry the battered fish in batches for even cooking.
  • Toss the sauce – Cook the sauce then add the fried fish and gently toss to coat. Be careful not to break up the fish.
  • Use pineapple chunks – Pineapple adds extra sweetness and a tropical twist. Other veggies like bell peppers and onions are also classic.
  • Serve over rice – Steamed white rice or stir fried noodles are the perfect accompaniments. The rice soaks up the tasty sauce!

Cooking Tips and FAQs

Simple Way to Prepare Speedy Sweet n Sour Crisp Dory Fillets | Riri Secret Recipes

Can I use frozen fish? Yes, frozen fish fillets work well. Just thaw them overnight in the fridge before battering.

What if I don’t have pineapple? Bell peppers and onions will still be tasty. Or try mango or apple chunks.

Can I use chicken instead? You can, though you’ll miss the soft flaky texture of fish. Adjust cooking time.

How long does it keep? Store leftovers in the fridge up to 3 days. The sauce keeps 2 weeks. Reheat in the microwave.
