Chè Trôi Nước (Vietnamese Floating Rice Balls in Ginger Syrup)

Within the Vietnamese family of chè desserts, chè trôi nước is known for its soft glutinous rice dumplings served warm in fragrant syrup. Each rice ball has a tender, slightly chewy skin wrapped around a smooth sweet mung bean centre, then is simmered until it floats before being finished in palm sugar syrup infused with fresh ginger. The dish is soothing rather than heavy: caramel-like sweetness, gentle heat from the ginger, a lightly savoury note from salt, and richness from warm coconut milk. Toasted sesame seeds add a final nutty accent, making it a comforting dessert for sharing in small bowls.

Why this recipe works

  • Distinctive texture: Glutinous rice flour creates a soft, chewy wrapper around the smooth mung bean filling.
  • Balanced sweetness: Palm sugar gives the syrup caramel depth, while ginger and a little salt stop the dessert from tasting flat.
  • Reliable cooking cue: Boiling the dumplings until they float helps signal when the rice dough is cooked through before it absorbs the ginger syrup.

Authenticity notes

  • Floating rice balls: The name refers to the dumplings rising to the surface as they cook, a key cue in the traditional preparation.
  • Served warm: Chè trôi nước is typically spooned into bowls with ginger syrup, coconut milk and sesame rather than served chilled.

Ingredient notes

  • Use glutinous rice flour: Standard rice flour will not give the same elastic, chewy texture needed for the dumpling skins.
  • Choose fresh ginger: Firm fresh ginger gives the syrup a clean warmth and fragrance; older ginger can taste woody or dull.
  • Coconut milk finish: Richer coconut milk gives a creamier contrast, while lighter coconut drinks produce a thinner, more delicate topping.

Common mistakes

  • Dry or sticky dough: Add the warm water gradually and adjust only as needed; the dough should be smooth, pliable and easy to seal without cracking.
  • Boiling the syrup too hard: Keep the ginger syrup at a gentle simmer once the rice balls are added so the dumplings stay intact and tender.
  • Overheating coconut milk: Warm the coconut milk just until steaming rather than boiling, which helps keep it smooth.

Make-ahead tips

  • Best texture on the day: The rice balls are softest and most supple soon after cooking, though leftovers can be refrigerated in their syrup.
  • Reheat gently: Warm the rice balls slowly in the syrup until piping hot, adding a splash of water if the syrup has thickened.
  • Keep coconut milk separate: Store and warm the coconut milk separately, then spoon it over just before serving for the cleanest finish.

  1. Rinse the mung beans in a colander until the water runs mostly clear. Tip into a saucepan, cover with fresh water by a few centimetres, and bring to the boil. Reduce to a gentle simmer for 12 to 15 minutes until very tender, topping up with a splash of water if needed.
  2. Drain the beans well, then return them to the warm pan. Add 40 g palm sugar and a pinch of fine sea salt, then mash with a wooden spoon until smooth and cohesive. Spread on a plate and leave to cool until you can handle it comfortably.
  3. While the filling cools, peel the ginger and slice it thinly. In a large pot, combine 160 g palm sugar with 900 ml water and the ginger, then bring to a gentle simmer. Simmer for 10 minutes to infuse, then keep the syrup on a low heat.
  4. Roll the mung bean paste into 12 small balls. Put the glutinous rice flour in a mixing bowl and add the warm water gradually, mixing until a soft, smooth dough forms that does not crack when pinched. Cover the dough with a damp cloth while you shape the balls.
  5. Divide the dough into 12 pieces and roll each into a ball. Flatten one piece in your palm, place a mung bean ball in the centre, then pinch to seal and roll smooth again. Repeat with the remaining dough and filling, keeping the finished balls covered so they do not dry out.
  6. Bring a separate pot of water to the boil. Add the rice balls and stir gently once to prevent sticking, then boil for 4 to 6 minutes until they float and the skins look slightly translucent. Lift them out with a slotted spoon and slide them straight into the warm ginger syrup.
  7. Simmer the rice balls in the syrup for 5 minutes so they absorb the flavour. Warm the coconut milk in a small saucepan with a pinch of fine sea salt just until steaming, without boiling. Ladle the rice balls and syrup into bowls, spoon over coconut milk, and finish with roasted sesame seeds.

Recipe notes

Tips

  • If the dough cracks as you shape it, knead in a little more warm water, 1 teaspoon at a time, until it is pliable.
  • Keep the ginger syrup at a gentle simmer, not a rolling boil, so the rice balls stay intact and tender.
  • Food safety note: if serving to young children, older adults, pregnant people, or anyone immunocompromised, ensure the rice balls are cooked through and served piping hot.

Substitutions

  • Replace palm sugar with light brown sugar for a similar caramel note, though the syrup will be slightly less fragrant.
  • Replace coconut milk with coconut milk beverage for a lighter topping, but warm it gently so it does not split.

Storage

  • Refrigerate up to 2 days
  • Cool completely, then refrigerate the rice balls in their syrup in a sealed container. Reheat gently in a saucepan over a low heat until piping hot, adding a splash of water if the syrup has thickened; warm the coconut milk separately and spoon over to serve.
