How to Fold Jiaozi: Five Folds, One That Matters

Why folding is not optional

Most English-language dumpling tutorials treat folding as the fun part — the part where you make something pretty before it disappears into boiling water. That’s wrong. The fold determines:

• Seal integrity: a poorly pleated edge has air pockets that split in boiling water or dry out when pan-fried.
• Cooking geometry: a flat-bottomed crescent sits stably in a hot pan; a badly closed half-moon rolls and browns unevenly.
• Dough-to-filling ratio at the bite: the pleat is multiple layers of dough. Where you pleat matters for texture.

Learn one fold correctly before you try five. The rest of this guide is built around that principle.

Before you fold: the two things that matter more

1. Your dough must be rested

Dough straight from kneading is elastic — it fights you when you try to seal it. Rest it, covered, for at least 30 minutes. After resting, the gluten relaxes and the wrapper becomes cooperative. If your sealed edges keep springing open, the dough hasn’t rested long enough.

2. The filling quantity is fixed

One level teaspoon — roughly 8–10g — per wrapper. Not a rounded teaspoon. Not a tablespoon because you want “hearty” dumplings. Too much filling means you’ll stretch the wrapper to close it, which thins the dough at the seal and causes splitting. Too little and the dumpling is dough with an impression of filling.

Use a small spoon and be consistent. Your 30th jiaozi should look like your 5th.

The five folds

Fold 1: The simple press (半月形 — half-moon)

The baseline. No pleats. Fast. Produces a flat sealed edge.

1. Place wrapper on your left palm (reverse if left-handed). Spoon filling into centre.
2. Fold the wrapper in half, bringing the far edge to meet the near edge.
3. Press firmly along the edge, working from one end to the other. Apply pressure with thumb and forefinger — you are welding two layers of dough, not decorating a pie.
4. The result: a half-moon with a flat, pressed rim.

When to use it: boiled jiaozi where appearance is secondary. Fastest method for large batches. Holds well if the dough is properly hydrated. Not ideal for pan-fried — the thin pressed edge can crisp to a chip rather than a unified crust.

The failure mode: pressing too lightly at the ends, leaving a 3–4mm unsealed section that opens in the pot. Press the ends first before the middle.

Fold 2: The single-side pleat (单褶 — one-sided)

The step between the press and the full crescent. Useful for teaching yourself the pleating motion.

1. Complete steps 1–2 of the simple press, but do not press the edge closed yet.
2. Hold the dumpling in front of you, sealed edge pointing up. With your right thumb and forefinger, pinch the centre of the edge to anchor it.
3. Using your right thumb, push a small fold of the front layer toward the centre pinch point. Press it against the back layer to seal. That is one pleat.
4. Make 2 more pleats to the right of centre, each one pushing toward the right end.
5. Press the right end closed. Leave the left half flat (no pleats).

Result: one half pleated, one half flat. Not traditional, but the fold is structurally sound and the pleating motion is the same as for the full crescent. Use this as practice before moving to Fold 3.

Fold 3: The crescent pleat (月牙形 — the standard)

This is the fold. Every regional Chinese dumpling tradition has a version of this. It is what jiaozi looks like.

1. Wrapper on left palm, filling centred.
2. Fold in half, pinch the centre of the edge to anchor — do not press the full edge yet.
3. Right side first: hold the back layer flat with your left thumb. Using the right thumb and forefinger, pleat the front layer toward the centre in three folds — push, press, push, press, push, press. Each fold is roughly 4–5mm wide. The three folds should consume the right half of the front edge.
4. Press the right end firmly closed.
5. Left side: mirror. Three pleats toward the centre from the left end. Press the left end closed.
6. The pleated spine should stand up from the back flat layer. Press the spine down gently to confirm all pleats are sealed.

The finished shape: a crescent with a raised central ridge, flat base, pointed ends. It sits naturally flat on a surface. The pleated side faces toward you when the dumpling sits on the table — this is the top in traditional presentation.

The failure modes:

• Air in the pleats: press while pleating, not after. The air has to escape as you press each fold.
• Uneven pleating: first two folds too large, last fold tiny. Count three evenly — 4–5mm each. The wrapper is roughly 9cm across the fold; three pleats per side = 6 folds total consuming ~54mm, leaving a few mm at each end to seal.
• Wrapper stretching: you are overfilling. The wrapper does not stretch to accommodate — the seal fails.

Practice 20 with discarded dough before you use real filling. The motion is counter-intuitive for 10 minutes and then automatic.

Fold 4: The ingot (元宝饺 — New Year form)

Traditional for the Spring Festival. The shape imitates a gold ingot (元宝, yuánbǎo), which is why eating them at midnight carries prosperity symbolism in northern China.

1. Make the full crescent pleat (Fold 3).
2. Pick the dumpling up by its pointed ends.
3. Curve the two ends toward each other. The dumpling body will arch slightly.
4. Press the two pointed ends together — you are joining them so the dumpling forms a ring with a gap in the middle.
5. Pinch firmly. The two ends must be well-sealed or they will separate in the pot.

Difficulty note: this fold requires a good crescent first. If your crescent ends are not fully sealed and dry, the ingot join will fail. The ingot also needs slightly larger wrappers (10–11cm rather than 9cm) to leave enough length at the ends for the join.

When to use it: batch made specifically for New Year celebration. Time-consuming — do not attempt for a 100-piece weeknight batch. The fold does not change the taste; it changes the occasion.

Fold 5: The pleated boat (褡裢火烧 — guotie form)

Strictly speaking this is the guotie fold rather than jiaozi, but the technique is directly related and worth knowing here. The guotie is open at both ends, which is intentional — steam escapes, the filling contacts the pan directly.

1. Place filling in the centre of the wrapper.
2. Fold in half, but do not press the ends closed — press only a 3–4cm section in the middle.
3. Pleat the front layer toward the centre along the middle section, making 4–5 pleats.
4. Leave both ends entirely open.

When this goes into a hot oiled pan (filling side down for some preparations, flat base down for others), the open ends allow steam to escape and the filling to caramelise at the contact points. This is a different eating experience from boiled jiaozi — the open ends will be slightly crisp, the filling at each end slightly charred and intense.

Full guotie technique — the water-fry method — is covered in the guotie deep-dive.

The equipment you actually need

A short rolling pin (Chinese-style, 20–25cm, no handles): the standard Western rolling pin produces flat, even sheets. The Chinese short pin lets you roll from the edge inward, rotating the wrapper, producing thick-centre / thin-edge wrappers. This is not fussiness — the thick centre resists tearing under filling weight; the thin edge pleats without stacking too much dough in the seal.

You can use a standard rolling pin. The result will be slightly thicker at the edge than ideal. It works. Move to a short pin when you make jiaozi more than once a month.

A bamboo steamer (if steaming): must sit over water without touching it. Line with parchment or lightly oiled cabbage leaves. Metal steamers trap condensation and drip on the wrappers. Equipment buying guide at asian-food.store.

Nothing else: no dumpling mold, no crimping tool. These devices produce uniform, machine-looking jiaozi and teach you nothing about dough feel. The hand fold is the skill — it is also faster once you have it.

When the wrapper tears during folding

If the wrapper tears when you are pleating — not at the seal, but in the body — the dough is too thin or the filling is too wet.

Too thin: roll to 2–2.5mm for boiled, not less. Beginners often roll too thin trying to imitate restaurant wrappers. Restaurant wrappers are thin because they are made by people with 10,000 hours of practice who can fold without stretching. Your wrapper will stretch when you pleat, effectively thinning it further. Start thicker than you think.

Too wet filling: the most common cause of mid-wrapper tears is filling moisture migrating into the dough. This happens when you:

• Don’t salt-and-squeeze cabbage before mixing into pork
• Let assembled dumplings sit uncovered for more than 15–20 minutes before cooking
• Use a filling with high liquid content (fresh tofu, undrained mushrooms)

The full analysis is in the why dumpling skins tear guide.

Sequence for a first batch

1. Make dough. Rest 30 minutes under a damp cloth.
2. Make filling. Refrigerate.
3. Roll 5 wrappers. Fold 5 dumplings using Fold 1 (simple press). Understand the dough.
4. Roll 5 more. Try Fold 3 (crescent). Expect 2–3 failures. Keep going.
5. By wrapper 20, the fold is becoming automatic.
6. Cook the first 10 immediately — do not let assembled dumplings sit longer than 20 minutes if the filling is wet.

One batch = 40–50 dumplings = 30–40 minutes of folding once you are past the learning phase. The first batch will take longer. That is the cost of learning a real skill.
