Suan cai yu is fish in a sour mustard-green broth. The fish flesh is sliced separately from the head and bones used for broth, and the sour vegetable supplies more than chili heat. Use pickled mustard greens rather than importing a cucumber-salad method.
Quick Answer
Separate thin fish slices from broth bones, prepare pickled mustard greens and aromatics, simmer the broth first and then cook the fish slices gently to a safe endpoint. Do not equate a thirty-second color change with a universal safe cooking time.
Basic Facts
| Fish | One fish about 800–1000 g, preferably filleted by a fishmonger; reserve suitable head/bones for broth |
|---|---|
| Sour vegetable | 1 cup pickled mustard greens |
| Liquid | About 800 ml water, adjusted to pot and fish |
| Aromatics | About 2.5 cm ginger; 4 garlic cloves; scallions; Sichuan peppercorns and dried chili to taste |
| Slice coating | 1 egg white, 2 tablespoons starch and 1 teaspoon white pepper from the cited version; salt adjusted to pickled greens |
| Safe endpoint | Fish reaches 63°C/145°F, or flesh is opaque and separates readily with a fork |
| Selected cooking oil | 2 tablespoons neutral oil divided between greens/aromatics and broth bones; no hot-oil finish |
Step-by-Step Sichuan Pickled Vegetable Fish Recipe
Use 5 scallions, keeping the whites for the aromatic stage and some chopped greens for serving. Start with about 10 Sichuan peppercorn husks and a small amount of dried chili pieces according to their heat. These are aromatics, not a substitute for the sour mustard. This version omits the soy sauce listed separately in the source ingredient card; taste the actual greens and broth before adding salt.
Set aside the sliced fish flesh separately from suitable head and bones. Remove visible pin bones and have a fishmonger prepare the fish if needed. Cut the pickled mustard greens into manageable pieces and drain according to the product directions. Prepare ginger, garlic and scallion before the broth stage.
The main ingredients are fish and sour preserved mustard greens. Do not replace them with chilled cucumber or chicken. The listed water amount is a starting quantity, not a requirement that every pot has the same broth depth. Pickled-green salinity varies, so taste the broth before adding additional salt.
How Fish Slice Prep Relates to Pickled Greens
Cut the fillet into thin reasonably even slices using a clean stable board. Mix with egg white, starch, white pepper and an appropriate small amount of salt; keep chilled while preparing the broth. Egg white is a coating ingredient, not a cold garnish, and must be cooked with the fish.
Keep raw fish away from the final serving bowl and prepared garnishes. Rinsing or marinating does not establish safe doneness. The sour greens should be the labelled pickled mustard product; dried mei gan cai and salty chopped ya cai are not interchangeable with it. Buy a commercially prepared sour mustard-green product and follow its label; this recipe does not establish a home-fermentation process.
Practical Checks for Sour Broth and Cooking Time
For this home adaptation, reserve 2 tablespoons neutral oil for cooking: use 1 tablespoon for the drained greens and aromatics and 1 tablespoon for the fish head and bones. The source lists 4 tablespoons oil with a separate hot-oil finish; that finish and its extra oil are omitted here. Cook the drained greens and aromatics until fragrant without scorching. Brown suitable fish head and bones in a separate stage, combine with the greens and water and simmer to make broth; about fifteen minutes is the cited starting broth stage. Remove or clearly manage the broth bones before serving fish flesh.
Add the chilled fish slices to gently simmering broth in small manageable additions. Cook to 63°C/145°F, or until flesh is opaque and separates readily with a fork. Thickness, batch size and broth temperature affect time. The source’s very short thin-slice timing is not a safe universal timer for every fillet. Adjust sourness and salt only after tasting the actual broth.
Mistakes, Serving Texture, and Food Safety
Serve the cooked slices with the sour greens and broth. Avoid vigorous prolonged boiling after the fish is cooked. Optional dried chili, peppercorn and scallion may provide aroma, but they do not replace the sour mustard component. This home version omits the hot-oil pouring finish; omitting that optional handling step leaves the dish recognizable.
Use clean serving tools, identify bones and refrigerate leftovers promptly. Fish, egg and any soy-containing additions are allergens to consider. A mild-looking broth is not evidence of underseasoning, and a red broth is not evidence of authenticity or safe fish. Keep fish slices intact by using a roomy pot and gentle movements when transferring them.
Quick reference
Fish and sour pickled mustard greens; broth before flesh; thin slices coated and kept chilled; safe doneness instead of a universal short timer. Manage bones explicitly.

Frequently Asked Questions
Can I use any preserved vegetable?
Not without changing the dish. This version uses sour pickled mustard greens, not ya cai, mei gan cai or cucumber.
Must fish cook for exactly thirty seconds?
No. Slice thickness and broth conditions differ; use a safe endpoint.
Are bones served as fish slices?
No. Broth bones and edible fillet slices are separate preparations; remove or clearly manage bones.
Must I pour hot oil over the bowl?
No. That is an optional finishing technique omitted from this version.
Why taste before salting?
Pickled greens already contain salt, and their strength varies by product.
