Chinese · Medium · Makes 16 balls

The dim sum trolley's golden sphere and the glutinous rice's own showpiece: the hollow-centred sesame ball — the thin, chewy glutinous shell blistered to the golden crisp, the sesame's toast over the sweet paste's hidden centre, and the hollow's own magic at the fry's patient swell. The jian dui's whole engineering is the fry's gentle psychology: the ball persuaded to double its size at the oil's patience, the hollow the swelling's own dividend.

Quantities live in the recipe card.

The dough

or the plain water's honest argument)

The filling

The coat and the fry

- The dough's hot-water law and its rest: the sugar dissolved in the hot water and the sweet liquid kneaded into the flour (with the pumpkin's mash if running) to the smooth, pliant dough — the hot water's gelatinisation the dough's own flexibility, the cold-water dough the crack's first cause — the dough rested 30 minutes, covered. - The sesame's double-dip adherence: the rolled balls dampened (the water's light mist or the damp palm's pass) and rolled in the sesame with the palm's pressing firmness — the seeds pressed into the dough's surface, not lying on it; the loose sesame the oil's scorched sediment's own cause.

Step 1. The shaping — the paste's hidden centre. The rested dough divided to 16 pieces (about 23 g each), each flattened to the disc's palm and the paste ball centred — the dough drawn up and sealed at the top's pinch, and the seam's thick knot pressed flat to the ball's even round (the thick seam the lopsided swell's own cause). Checkpoint — each rolled ball runs the even wall's thickness and the paste's hidden centre at the ball's core — a visible seam's thick spot the fry's uneven swell already chosen, and the ball's smooth round the hollow's even argument.

Step 2. The gentle fry and the swell's patience — 12–15 minutes at the 150 °C persuasion. The oil at the 150 °C gentle heat (the ball's entry the slow, small bubble — never the fierce fry), and the balls lowered in the small batches — the fry's whole discipline at the patience: the balls left to the oil's gentle warmth 5 minutes, then the persistent pressing (the sieve's or the ladle's gentle hold, the balls pressed under the surface and released — the press-and-release's ten repetitions the swell's own persuasion), the oil's heat rising to 170 °C through the final 5 minutes to the deep golden swell. Checkpoint — at the press-and-release's work the balls swell visibly to near-double their entry's size — the hollow forming at the dough's inner steam — and the finished ball runs the blistered, even deep gold with the sesame's toast at the nose; the pale small ball the patience's refusal, the dark-cracked one the heat's excess.

Step 3. The drain and the service. The golden balls lifted to the paper's drain and rested 5 minutes (the hollow's own setting and the shell's crisp) — served warm, the first ball's crack the hollow's own proof. Checkpoint — the eating test: the shell's blistered crisp giving to the glutinous chew's elastic curtain, and the hollow's chamber (the ball's inner steam's architecture) breaking to the paste's sweet centre — the jian dui's whole argument in the one bite, and the solid-centred ball the swell's doctrine's own failure. Chef’s Note — the press-and-release's ten repetitions is the hollow's whole engineering and the dim sum kitchen's own open secret: the ball's inner steam (the dough's moisture and the paste's own) inflates the ball only while the oil's heat reaches the centre — and the pressing's gentle submersion forces the hot oil's contact over the ball's whole surface while the release lets the steam's pressure expand the softened wall. The patient 150 °C persuasion and the rising finish run the fry's psychology: the low heat's stretch, the high's gold — and the hurried fierce fry the small, solid, cracked ball's own certain end.

Sesame Balls (Jian Dui)

Prep: 40 minutes, plus 30 minutes resting · Cook: 20 minutes · Total: About 1 hour 30 minutes · Makes 16 balls

Ingredients

The dough

200 g glutinous rice flour
60 g caster sugar, dissolved in 130 ml hot water
30 g mashed cooked pumpkin or sweet potato (the traditional swelling's aid — or the plain water's honest argument)
1 tbsp (15 ml) neutral oil

The filling

150 g red bean paste or lotus seed paste, rolled to 16 small balls (about 9 g each)

The coat and the fry

100 g white sesame seeds (the hulled's even gold)
1 litre neutral oil, for the frying at the gentle 150–170 °C window

Instructions

The shaping — the paste's hidden centre. The rested dough divided to 16 pieces (about 23 g each), each flattened to the disc's palm and the paste ball centred — the dough drawn up and sealed at the top's pinch, and the seam's thick knot pressed flat to the ball's even round (the thick seam the lopsided swell's own cause). Checkpoint — each rolled ball runs the even wall's thickness and the paste's hidden centre at the ball's core — a visible seam's thick spot the fry's uneven swell already chosen, and the ball's smooth round the hollow's even argument.
The gentle fry and the swell's patience — 12–15 minutes at the 150 °C persuasion. The oil at the 150 °C gentle heat (the ball's entry the slow, small bubble — never the fierce fry), and the balls lowered in the small batches — the fry's whole discipline at the patience: the balls left to the oil's gentle warmth 5 minutes, then the persistent pressing (the sieve's or the ladle's gentle hold, the balls pressed under the surface and released — the press-and-release's ten repetitions the swell's own persuasion), the oil's heat rising to 170 °C through the final 5 minutes to the deep golden swell. Checkpoint — at the press-and-release's work the balls swell visibly to near-double their entry's size — the hollow forming at the dough's inner steam — and the finished ball runs the blistered, even deep gold with the sesame's toast at the nose; the pale small ball the patience's refusal, the dark-cracked one the heat's excess.
The drain and the service. The golden balls lifted to the paper's drain and rested 5 minutes (the hollow's own setting and the shell's crisp) — served warm, the first ball's crack the hollow's own proof. Checkpoint — the eating test: the shell's blistered crisp giving to the glutinous chew's elastic curtain, and the hollow's chamber (the ball's inner steam's architecture) breaking to the paste's sweet centre — the jian dui's whole argument in the one bite, and the solid-centred ball the swell's doctrine's own failure.

Troubleshooting

Symptom	Cause	Fix
Balls small and solid	The press-and-release skipped, or the heat fierce	The ten repetitions; the 150 °C patience's stage
Shells burst at the fry	The seam's thick knot, or the dough cracked	The even wall's shaping; the hot-water dough's rest
Sesame's scatter to the oil	The seeds lying loose, unpressed	The damp roll and the palm's pressing firmness

Storage, Make-Ahead & Variations

- The balls serve the fry's warm hour — the hollow's argument and the shell's crisp same-day; the second day's ball re-fries to a fair chew (the hollow's softer echo) at 170 °C for 2 minutes. The dough's ball holds 1 day refrigerated for the on-demand shaping. - The filling's canon runs the red bean's and lotus paste's sweet standards and the black sesame's own toasty register; the pumpkin's mash in the dough (the record's 30 g) is the swelling's traditional aid at the autumn's own colour. The same glutinous dough's family runs the mochi's plain chew and the tangyuan's soup-borne cousin.
