First, you can use either freshwater or saltwater fish. Yellow Croaker is the most popular fish choice, which is a saltwater fish. Butterfish is the other most suitable saltwater fish. Perch and crucian are among the most suitable freshwater fish.

A suitable whole fish for Huai Yang Sweet and Sour style typically weighs between 0.5 lb to around 1 lb that has a tender, flaky, yummy white meat.

How to make a tasty, healthy, Sweet and Sour fish in less than 15 minutes?
See the Recipe for a detailed step-by-step tutorial. Here are key tips and tricks.
The first is to coat whole fish with arrowroot flour prior to cooking
Clean and rinse the fish well. Pat dry with a paper towel and then sprinkle the fish with a pinch of salt evenly. After that coat the fish, both sides, with a thin layer of arrowroot flour. Gently pat to rub into fish.

The Second is to sear the fish on both sides before braising

Turn the heat to medium, heat a hard anodized fry-pan for 1 minute, and then add oil, green onions and ginger. Stir for about 10 seconds or till fragrant and then lay fish flat flat onto the pan one by one. Cook for 2 minutes. Following that, flip the fish and cook the other side for another 2 minutes.
Traditional vs. Simplified Huai Yang Style Sweet and Sour Fish
Sweet and Sour Yellow Croaker is a very traditional well-liked Huai Yang style dish. The traditional cooking method usually pan fry to cook the fish using simmering heat first and then pour the heated sauce over. This method usually takes about 30 minutes, instead of 15 minutes using braising method.
For the traditional method, we also do extra prep work on fish. For instance, we usually stuff fish rib cage with thinly sliced ginger and green onions.
In summary, traditional method Huai Yang style requires more prep work, takes longer to cook, and the fish meat has more satisfying firm bite flaky texture. The simplified method doesn’t require lots of preparation and cooks the fish in under 15 minutes.
