Smooth white kidney bean paste sweetened with sugar and osmanthus syrup, rolled tightly into a chilled cylinder and sliced into pale ivory rounds—a cool, subtly sweet Beijing snack long associated with Empress Dowager Cixi and the imperial kitchen tradition.
A cool-served Beijing snack made from white kidney beans, 芸豆卷 is widely recounted in Beijing culinary literature as a dish that street vendors sold near the imperial parks. The most commonly cited story holds that Empress Dowager Cixi heard a vendor's call during an outing, tasted the roll, and was so taken by it that she had the palace kitchen incorporate it into the regular imperial menu. This account appears in multiple Beijing food chronicles and local records, though no direct citation in verified Qing palace archives has been established; it should be treated as well-attested local tradition rather than confirmed history. After the fall of the Qing dynasty, 芸豆卷 returned from the palace kitchens to the city's street food circuit, becoming a fixture at Huguo Temple and Longfu Temple snack markets.
Each pale ivory slice is silky-dense and cool, dissolving on the tongue with a gentle bean sweetness lifted by the floral warmth of osmanthus—quiet, refined, and not remotely cloying.
Dried white kidney beans contain approximately 46g starch and 22g protein per 100g dry weight. Prolonged simmering fully gelatinizes the starch granules and ruptures cell walls, releasing starch into a smooth, uniform paste. As the mashed paste cools, linear amylose chains rapidly retrograde and entangle, while amylopectin chains crystallize more slowly—together forming a starch gel network firm enough to roll and slice cleanly without any added gelatin or agar. The lower the water content in the mashed paste, the denser the gel network and the cleaner the slice face. Sugar molecules from the osmanthus syrup embed in the network interstices, adding sweetness while mildly slowing further retrogradation.
Variations
Some versions roll a layer of sweetened red bean paste inside for a two-toned cross-section; matcha powder or purple sweet potato paste can be blended into part of the bean paste for color contrast; a savory version substitutes salt and toasted sesame oil for the sugar.

Ingredients
Serves 6How it's made
8 steps · 20 min
- 12 min
Drain 300g white kidney beans that were soaked overnight (at least 8 hours) in cold water.
- 270 min
Place the drained beans in a pot, cover with fresh water by 5cm, bring to a boil, then reduce heat and simmer for 60–80 minutes until completely tender and the skins slip off easily.
Watch outSimmer the beans a full hour-plus until they're falling-apart soft and the skins slip — undercooked starch won't set into a sliceable gel.
- 315 min
Drain thoroughly; while still warm, press the beans through a fine-mesh sieve or food mill to obtain a smooth, completely lump-free paste.
Watch outSieve the beans while still warm into a completely lump-free paste — any lumps left behind crack the slice face when you cut the roll.
- 45 min
Stir 80g powdered sugar and 2 tbsp osmanthus syrup into the warm paste until evenly combined; taste and adjust sweetness.
- 55 min
Lay a 40cm sheet of plastic wrap on a flat surface. Spread the bean paste in an even layer about 1cm thick across the centre of the wrap.
- 63 min
Using the wrap as a guide, roll the paste into a tight, compact cylinder; twist both ends firmly to seal and compress the roll.
Watch outRoll the paste into a tight, compact cylinder with no air pockets — a loose roll slumps and slices ragged instead of clean rounds.
- 7120 min
Refrigerate for at least 2 hours (overnight is ideal) until fully set and firm.
- 85 min
Unwrap, trim the ragged ends, and slice into rounds approximately 1.5cm thick; arrange on a chilled plate and serve cold.
