Dried fish maw looks small in the bag, but it does not stay that way. Once it is soaked, it takes on water and grows several times its dry weight and volume, which throws off portion planning if you have not worked with it before. Here is what to expect from 100 g of dried fish maw, from soaked weight to bowls of soup.
Key Takeaways
- 100 g of dried fish maw generally yields around 220-260 g once fully soaked, roughly 2.2 to 2.6 times its dry weight
- The volume increase is even more noticeable than the weight increase, since soaked fish maw is soft and smooth with a fine lengthwise grain
- 100 g dried is enough for roughly 4-6 small bowls of soup as a shared course, or fewer as a standalone banquet dish
- A 213 g box of TLY tube-cut or flat-cut fish maw soaks up to roughly 470-550 g, enough for a reunion dinner table of 6-10 people alongside other dishes
- Yield varies by thickness and cut: thin flat-cut pieces soak faster and expand slightly less than thick tube-cut pieces
Weight: Dry to Soaked
Dried fish maw is mostly collagen and connective tissue with very little moisture left in it, which is exactly why it can absorb so much water. As a rough planning number, 100 g of dried fish maw becomes about 220-260 g after a full overnight soak in cold water. Thicker tube-cut pieces tend to land at the higher end of that range, while thinner flat-cut pieces land closer to the lower end, since there is less dense material to rehydrate.
These figures are a planning guide, not a lab measurement -- actual yield shifts with soak time, water temperature, and the specific piece.
Volume Matters More Than Weight
Weight only tells part of the story. Soaked fish maw is soft, plump, and swollen with water, so a piece that looked like a folded sheet in the bag can fill a mixing bowl once it has taken on water. When you are estimating how much to buy for a soup or a banquet dish, think in terms of the finished bowl size, not just the gram count on the package.
How Many Bowls Does 100 g Make?
For a soup where fish maw is one component among several -- alongside broth, mushrooms, and other seafood -- 100 g dried (roughly 230-250 g soaked) typically stretches across 4-6 small shared bowls. If fish maw is the star of a standalone banquet dish, where guests expect a generous piece on their plate, the same 100 g may only cover 2-3 servings.
Typical Yield at a Glance
| Dried Weight | Soaked Weight | Shared Soup Bowls |
|---|---|---|
| 100 g | ~220-260 g | 4-6 bowls |
| 213 g (TLY box) | ~470-550 g | 9-12 bowls |
Planning for a Reunion Dinner
A standard 213 g box of TLY tube-cut or flat-cut fish maw soaks up to roughly 470-550 g, which is enough for a reunion dinner table of 6-10 people when fish maw is served as one dish among several courses. If you are planning a table where fish maw is the centerpiece dish, or you want generous portions with seconds, sizing up to two boxes is worth considering.
Trimming and Waste
Expect a small amount of trim loss once a piece is soaked and cleaned -- any tough edges or uneven bits are usually cut away before cooking, which can reduce usable weight by a small percentage. This is normal and does not mean the fish maw was flawed; it is simply part of prepping a piece for even cooking.
Storing Soaked Surplus
If you soak more than you need for one meal, drained soaked fish maw keeps in the refrigerator for a couple of days in a sealed container with a little water. For longer storage, soaked pieces can be frozen in a single layer, then bagged once solid, so they do not clump together.

Frequently Asked Questions
Does fish maw lose weight when cooked after soaking?
Cooked fish maw generally holds close to its soaked weight, since simmering does not drive off much of the absorbed water the way high, dry heat would.
Why does tube-cut soak up more water than flat-cut?
Tube-cut pieces are thicker and denser in their dry state, so they have more dry material to rehydrate, which pushes their soaked weight higher relative to their starting weight.
How much fish maw do I need per person?
As a rough guide, plan on 15-25 g dried fish maw per person when it is one course among several, and closer to 35-50 g dried per person if it is the featured dish.
Can I soak less than a full piece?
Yes. Dried fish maw can be cut into smaller sections with kitchen scissors before soaking, so you only rehydrate what you plan to use.
