Specialty Flours for Dumplings — Buying Guide
All-purpose flour makes decent jiaozi wrappers. It will not make har gow, tang yuan, or any translucent dumpling skin. Those require flours with specific starch compositions that behave completely differently from wheat protein flour. This guide covers the three you actually need, what each one does, and which brands to buy.
The Three Flours at a Glance
| Flour | What it is | Key property | Primary use |
|---|---|---|---|
| Wheat starch (澄麵) | Wheat flour with gluten washed out — pure starch | Turns translucent when cooked; no elasticity | Har gow wrappers, cheung fun, crystal dumplings |
| Tapioca starch | Starch extracted from cassava root | Adds chew and stretch; stays clear | Blended with wheat starch for har gow; cheung fun; boba pearls |
| Glutinous rice flour (糯米粉) | Ground short-grain glutinous rice — no actual gluten | Chewy, sticky texture when cooked; opaque white | Tang yuan, mochi, nian gao, some Sichuan dumplings |
Wheat Starch (澄麵 / Cheng Mian)
This is not flour in the normal sense. It is pure wheat starch — the protein (gluten) has been removed. Without gluten, the dough has no elasticity, tears if you try to stretch it, and must be worked with boiling water and speed. The payoff: translucent, silky wrappers that let filling color show through, which is the entire point of har gow.
Erawan Brand Wheat Starch — 400 g
The standard in Cantonese dim sum kitchens outside China. Consistent fine grind, minimal clumping, reliable translucency after steaming. The blue Erawan packaging is what you want — not their rice flour or tapioca, which look similar.
Trade-off: Requires boiling water technique — the starch gelatinizes during mixing, which is what makes it workable. Room-temperature water produces crumbly, unusable dough.

Dragonfly / Double Swallow Wheat Starch — 400 g
Common alternative in European Asian grocery stores. Comparable performance to Erawan. If you can only find this locally, it works — the har gow ratio (3 parts wheat starch : 1 part tapioca) applies identically.
Trade-off: Slightly less consistent grind than Erawan; sift before measuring to avoid lumps in the final dough.

Tapioca Starch
Tapioca starch is rarely used alone in dumpling making — it is almost always blended with wheat starch. Its job is to add cohesion and chew to a wheat starch dough that would otherwise be brittle. The classic har gow ratio is 3:1 wheat starch to tapioca starch. You can push to 2:1 for chewier wrappers (though authenticity drifts toward chewy if you go further).
Erawan Brand Tapioca Starch — 400 g
Same manufacturer as the wheat starch above. Using both from the same brand ensures consistent grind size, which matters for even gelatinization. Pure cassava starch, no additives.
Trade-off: Interchangeable with other brands for this application. Tapioca starch is a commodity — quality differences between reputable brands are minimal. Price comparison makes sense here.

Glutinous Rice Flour (糯米粉 / Nuo Mi Fen)
Despite the name, glutinous rice flour contains no gluten — "glutinous" refers to its sticky behavior when cooked. It is ground from short-grain sticky rice. The cooked texture is chewy, dense, and opaque — the opposite of wheat starch wrappers. This is what makes tang yuan (filled rice dumplings eaten in broth or sweet syrup), mochi, and nian gao. Do not confuse with regular rice flour (ground from non-glutinous rice) — they behave completely differently.
Erawan Brand Glutinous Rice Flour — 400 g
Standard in Southeast Asian and Chinese cooking. Fine, consistent grind. Works reliably for tang yuan dough (mix with boiling water to rough ratio of 5:3 flour to water by weight, adjust for pliable but not sticky dough).
Trade-off: Absorbs water differently in humid vs. dry kitchens. Add water incrementally — the last 10% of liquid makes the difference between workable dough and paste.

Mochiko (Koda Farms) — 454 g
Japanese sweet rice flour — the same product, different origin grain and slightly different water absorption. Works for tang yuan and mochi equally. Mochiko is finer than most Chinese glutinous rice flours and produces a slightly smoother, more consistent dough. Easier to source in Germany via Amazon.
Trade-off: More expensive than Chinese brands per gram. For mochi and Japanese wagashi, the finer grind is worth it. For tang yuan at volume, stick with Erawan.

What You Actually Need to Buy
- Making har gow or crystal dumplings: Wheat starch + tapioca starch. Both are required — neither works alone for this application.
- Making tang yuan, mochi, or nian gao: Glutinous rice flour only. No wheat starch or tapioca involved.
- Making cheung fun (rice noodle rolls): Wheat starch + tapioca + regular (non-glutinous) rice flour. Different application — see the knowledge graph.
- Don't confuse: Regular rice flour (not sticky, used for rice noodles) vs. glutinous rice flour (sticky, used for mochi/tang yuan). The bags look similar; read the label.
Har Gow Wrapper Ratio (Quick Reference)
Standard dim sum ratio per 100 g total flour: 75 g wheat starch + 25 g tapioca starch. Add 85–90 ml boiling water, work quickly, cover immediately. Rest 5 minutes under damp cloth before rolling. Roll between oiled plastic wrap — wheat starch dough tears on dry surfaces.
