A Huizhou New Year confection: sweet pork-fat and sugar balls are rolled repeatedly in wild-harvested kudzu starch until encased in a thick chalky coat, then steamed until the outer shell turns translucent dark-brown and shiny — a once-a-year symbol of family reunion.
Kudzu root is a traditional mountain foodstuff in Huizhou, where farmers dig the wild roots after autumn and process them — pounding the fresh roots, washing the starch through clean water, settling and sun-drying — into a white 'mountain starch' that once served as a lean-season substitute for grain. The custom of rolling sweet dumplings in this starch as a New Year offering has been handed down in the mountain villages for, by local reckoning, close to a thousand years. Because of their round shape and the auspicious meaning of 圆 (complete, united), kudzu-starch dumplings became an enduring symbol of reunion at the New Year feast.
The outer shell is dense and chewy — somewhere between glutinous rice skin and thick glass-noodle texture — with a faint cool, grassy note from the kudzu. Bite through and the centre yields a rush of warm, sweet lard.
Kudzu starch has a higher amylose content than ordinary wheat or rice starch. During steaming, the starch granules hydrate, swell and gelatinize; amylose chains leach out and form a dense gel network that turns the outer layer from chalky white to translucent dark-brown — the visual signal of full doneness. The same dense gel gives the skin its resilient, glass-noodle-like chew. Small surface bubbles confirm that steam has penetrated the crust all the way to the filling. Isoflavones naturally present in kudzu root leach partially into the skin during steaming, lending a faint herbal bitterness at the finish.
Variations
Sweet alternatives use red bean paste or osmanthus sugar as filling; savory versions substitute minced pork, preserved mustard greens and five-spice. Some households blend a small amount of rice flour into the kudzu starch to lighten the skin texture.

Ingredients
Serves 4How it's made
6 steps · 30 min
- 130 min
Sift kudzu starch powder to remove any lumps; if using fresh kudzu root, pound, wash, settle and sun-dry following the traditional method to obtain white starch powder.
- 215 min
Make the filling: finely mince pork fatback; mix with white sugar and osmanthus sugar until combined. Roll into balls approximately 2 cm in diameter; chill for 30 minutes until firm.
- 310 min
Pour a generous amount of kudzu starch into a shallow dish. Roll each filling ball in the starch until evenly coated; press gently to adhere, then return to the dish and roll again. Repeat 3–4 times to build a thick, even white crust.
Watch outRoll and re-roll to build 3–4 thick, even coats — a thin patchy shell cracks in the steamer and the sugar filling leaks out.
- 45 min
Line a steamer basket with damp cloth; arrange coated dumplings with space between them, placing them in a circular pattern to symbolise reunion.
- 518 min
Steam over vigorously boiling water on high heat for 15–20 minutes until the outer coating turns translucent dark-brown and shiny with small bubbles on the surface.
Watch outIt's done the instant the coat turns from chalky white to translucent dark-brown with tiny surface bubbles — that color flip is the doneness signal.
- 63 min
Serve immediately in the steamer basket while hot; the skin softens as it cools, so eat promptly.
Watch outEat it straightaway while the skin is springy — as it cools the coat stiffens and loses that glassy chew.
