Sesame Balls Recipe (Jian Dui – Authentic Hong Kong Dim Sum)
Sesame balls (known in Cantonese as Jian Dui) are one of the most beloved traditional dim sum desserts across Hong Kong, Southern China, and beyond. With their crisp, golden sesame coating, soft yet delightfully chewy glutinous rice crust, and sweet, smooth filling, they strike the perfect balance of textures and flavors. More than just a snack, they carry cultural meaning: their round shape symbolizes unity and completeness, while their glossy golden exterior represents prosperity and good fortune, making them a favorite treat during festivals, family gatherings, and everyday meals alike.

🛒 Ingredients
For the Glutinous Rice Dough
This is the foundation of the perfect Jian Dui; soft, elastic, and strong enough to hold its shape while frying:
- 2 cups glutinous rice flour (essential for the authentic chewy texture)
- ¾ cup warm water (about 40–45°C / 105–115°F)
- ¼ cup granulated sugar
- 1 tablespoon neutral vegetable oil
For the Sweet Filling
- 1 cup smooth sweet red bean paste
- 1 tablespoon water (optional, only if the paste is too firm to shape)
For Coating and Frying
- 1 cup white sesame seeds, rinsed and lightly patted dry
- Enough neutral oil for deep frying
👩🍳 Step-by-Step Method
Step 1: Make the Dough
In a large mixing bowl, combine the glutinous rice flour and sugar. Make a well in the center, then gradually pour in the warm water and oil. Mix gently at first, then knead with your hands until you get a smooth, soft, and non-sticky dough. If it feels too dry, add a teaspoon more water; if too sticky, dust lightly with extra flour. Cover the dough with a clean damp cloth and let it rest for 10 minutes; this helps relax the gluten, so it stretches easily later.
Step 2: Prepare the Filling
While the dough rests, divide the red bean paste into 12 equal portions, roughly 1 tablespoon each. Roll each portion into a neat ball. If the paste is stiff, knead in a small amount of water to soften it slightly; this makes shaping easier and prevents cracks later.
Step 3: Shape the Balls
Divide the rested dough into 12 equal pieces. Take one piece and flatten it gently between your palms or roll it into a small disc about 3 inches wide, keeping the center slightly thicker than the edges. Place one ball of red bean paste in the middle. Slowly pull the edges of the dough upward and wrap them around the filling, pinching tightly to seal completely. Roll it gently between your palms to form a smooth, round ball. Repeat with all portions.
Step 4: Coat with Sesame Seeds
Lightly moisten the surface of each dough ball with a little water; this helps the sesame seeds stick. Place the sesame seeds in a shallow plate, then roll each ball over them until fully and evenly coated. Press lightly so the seeds adhere firmly and do not fall off during frying.
Step 5: Heat the Oil
Pour oil into a deep pot or wok until it reaches about 2–3 inches deep. Heat it over medium-low heat until it reaches 150°C / 300°F. This lower starting temperature is key; it allows the dough to expand slowly and evenly without bursting.
Step 6: Fry Gently
Carefully lower 3–4 balls into the oil at a time; do not overcrowd the pot, as this will lower the temperature too quickly and result in uneven cooking. Fry them slowly, turning them constantly with a slotted spoon. You will notice them gradually rise to the surface and begin to puff up.
Step 7: Increase Heat for Crispness
Once the balls have fully expanded and are floating steadily, slightly raise the heat to medium. Continue turning them regularly until they turn a rich golden-brown and feel firm yet light to the touch. This final stage ensures the exterior becomes crisp while keeping the inside soft and chewy.
Step 8: Drain and Serve
Remove the sesame balls from the oil and let them drain on a wire rack or paper towels to remove excess oil. Serve them while still warm; this is when their texture and flavor are at their absolute best.
💡 Pro Tips for Perfect Jian Dui Every Time
- Use the right flour: Only glutinous rice flour will give you that signature chewy bite; regular rice flour will result in a hard, dense texture.
- Seal well: Any small gap or crack will cause the filling to leak out and the balls to burst while frying.
- Control the temperature: Start low and finish slightly higher; this is the most important rule for proper expansion.
- Turn often: Rotating the balls ensures they puff evenly and keep their round shape.
- Serve fresh: If left to cool completely, the crust may soften; reheat briefly in an oven or air fryer to restore crispness.
❌ Common Mistakes to Avoid
- Oil too hot at the start: Causes the outside to brown too fast while the inside remains raw and often leads to bursting.
- Dough rolled too thin: Weakens the structure and makes leaks more likely.
- Insufficient sealing: Even a tiny opening can let oil seep in or filling escape.
- Overcrowding the pot: Drops the oil temperature and makes the balls greasy and misshapen.
- Skipping the resting time: Makes the dough less elastic and harder to shape without cracking.
📜 Background & Cultural Significance
Jian Dui is not just a recipe; it is part of the culinary heritage of Southern China and Hong Kong.

❓ Frequently Asked Questions
Q: Can I use other fillings instead of red bean paste?
A: Absolutely! Popular alternatives include smooth lotus seed paste, black sesame paste, mung bean paste, or even chopped roasted peanuts mixed with sugar.
Q: Why did my sesame balls burst while frying?
A: This usually happens because the oil was too hot at the beginning, the dough was rolled too thin, or there was a gap in the sealing.
Q: Can I make these in an air fryer instead of deep frying?
A: While possible, the texture will differ; deep frying allows the dough to expand evenly and creates that signature crisp-chewy balance. If air frying, spray generously with oil and cook at 160°C / 320°F, turning often, but expect a slightly denser result.
Q: How should I store leftovers?
A: Let them cool completely, then keep in an airtight container at room temperature for up to 2 days. To reheat, place in a preheated oven or air fryer at 150°C / 300°F for 3–5 minutes until crisp again.
Q: Why didn’t my balls puff up?
A: The most common reason is starting with oil that is too hot; the crust hardens before the inside has a chance to expand. Always begin at a lower temperature.
