Best for fish maw soup

Substitutes for Fish Maw with ratios

  1. 2Dried pork skin, rehydrated (or simmered pork rinds)

    Different taste

    Use the same amount by rehydrated weight

    Soak dried pork skin overnight, or simmer plain pork rinds for 20 minutes until soft and spongy, then cut into strips and add with the rest of the soup.

    What changes

    This is the closest match for the specific gelatinous, slippery-spongy bite people are actually chasing.

    Best for
    thick soups, braises, claypot dishes, recipes where the broth should feel rich

    Because it is collagen, it does the second thing fish maw does: it dissolves a little and gives the broth a faintly sticky richness. The trade-off is flavor, since pork skin tastes of pork and releases fat. Blanch it first and skim the soup, and skip this one if the dish is meant to be all seafood.

  2. 3Tofu puffs

    Different texture

    Use the same amount by volume

    Halve them and add in the final 5 minutes so they soak up broth without collapsing.

    What changes

    Cheap, sold in every Asian grocery, and no soaking needed.

    Best for
    quick weeknight soups, hot pot, vegetarian versions

    You get the sponge, not the slip. Tofu puffs are much softer than fish maw and have no springy resistance at all, so a soup made with them feels comforting rather than luxurious. They also fall apart if simmered longer than about 10 minutes.

  3. 4Rehydrated or prepared sea cucumber

    Different texture

    Use the same amount by rehydrated weight

    If your grocer sells prepared or frozen sea cucumber, it sits in the same family of collagen-rich, nearly flavorless banquet ingredients and is used in some of the same restaurant soups.

    What changes
    Best for
    banquet soups, special-occasion braises, recipes where the texture is the point

    Springier and more assertively bouncy than fish maw, with a faint mineral note fish maw does not have. It is usually just as expensive, so this is a swap for availability rather than price. Simmer it for less time than fish maw or it turns squeaky.

  4. 5Chicken feet or a piece of pork trotter, for the broth only

    Different taste

    Use 2 to 3 chicken feet for every 4 cups of broth

    Simmer them in the stock for 45 minutes and lift them out.

    What changes

    Use this when fish maw was in the recipe to make the soup feel full-bodied rather than to give you something to chew.

    Best for
    thick soups, broth-forward recipes, crab and fish maw soup

    This restores the collagen and the silky mouthfeel very effectively, but it puts nothing in the bowl, so pair it with sliced mushrooms, bean curd sticks or shredded crab if the recipe needs solids. It also adds a light poultry flavor, which is usually welcome in Cantonese soups.

  5. 6Leave it out and thicken the soup instead

    Different texture

    Use 1 tablespoon cornstarch whisked with 2 tablespoons cold water for every 4 cups of soup

    Fish maw is a garnish of texture in most recipes, so a thick crab or chicken soup is still a good soup without it.

    What changes

    Whisk the slurry into the simmering broth at the end.

    Best for
    crab and fish maw soup, chicken thick soup, weeknight cooking

    This is the honest answer if you have no specialty shop nearby, because nothing in a regular supermarket eats like fish maw. What you can copy is the body of the soup. Expect the dish to taste identical and feel slightly less interesting, since you have removed the one element that existed purely for mouthfeel.

What is Fish Maw?

Fish Maw is Fish maw, also sold as dried fish maw, fish bladder or yu du, is the cleaned and dried swim bladder of large fish such as croaker, catfish or sturgeon, sold as pale crisp sheets or tubes that are soaked and simmered until they turn soft and slippery.

Cooking tips

  • Fish maw is close to flavorless. If your soup tastes bland after swapping it out, the problem was never the fish maw, it was the broth. Fix it with dried scallop, dried shiitake soaking liquid, a piece of kombu, or a good pinch of white pepper.
  • Dried fish maw is soaked overnight and then blanched with a slice of ginger and a splash of Shaoxing wine to clear any lingering fishy smell. Any dried swap, such as bean curd sticks or pork skin, benefits from exactly the same ginger blanch.
  • Everything in this family goes from pleasantly slippery to mushy quickly. Add rehydrated bean curd sticks, tofu puffs or pork skin in the last 10 minutes rather than at the start of a long simmer.
  • Cut your substitute to the size the recipe wanted the fish maw, usually 1 to 2 inch pieces. Texture ingredients read as luxurious partly because of how big they are on the spoon.
  • Pork rinds are a good stand-in but they are salty. Simmer them in plain water for 10 minutes first, discard that water, and salt the soup at the end rather than the beginning.

Frequently asked questions

Can I just leave fish maw out?

Yes, in almost every recipe. Fish maw contributes texture and a little collagen body, not flavor, so a crab thick soup or a claypot braise without it is still complete. Add a cornstarch slurry at the end to restore the thickness and the dish will read as very close to the original.

What does fish maw actually taste like?

Almost nothing on its own. Properly cleaned fish maw is neutral and simply absorbs whatever broth it cooks in. That is exactly why it appears in expensive soups: it delivers a slippery, faintly springy bite and lets the stock do all the talking.

Is fish maw the same thing as fish bladder?

Yes. Fish maw, dried fish maw, fish bladder and the Cantonese yu du all refer to the dried swim bladder of a fish. It is sold in several grades, from thin flat sheets to thick puffed tubes, and the thicker grades stay chewier after a long simmer.

What is the cheapest substitute for fish maw?

Dried bean curd sticks, by a wide margin. A bag costs very little, keeps for months in the pantry, and after an hour in warm water gives you the silky-but-springy texture that is the whole point of fish maw.

Is there a vegetarian substitute for fish maw?

Rehydrated bean curd sticks or tofu puffs, both fully vegetarian and both already common in Chinese vegetarian cooking. Skip the pork skin and chicken feet options and build body into the broth with dried shiitake soaking liquid and a strip of kombu instead of collagen.
