Ingredients
  

Lava Filling

  • 80 g roasted peanuts
  • 60 g roasted black sesame seeds
  • 60 g granulated sugar
  • 80 g lard or 80g butter as substitute
  • 60 g honey

Tangyuan Dough

  • 400 g glutinous rice flour water-milled preferred
  • 160 g boiling water
  • 140 g cold water
  • 20 g dry glutinous rice flour for dusting

Tools

  • 1 food processor or blender
  • 2 mixing bowls
  • 1 tray lined with parchment
  • 1 damp towel
  • 1 pot
  • 1 silicone spatula

Instructions
 

Step 1: Prepare the Lava Filling (Freezing Is Key)

  • Add 80g roasted peanuts and 60g roasted black sesame seeds into a food processor. Pulse until finely ground. A slight texture is good — don’t over-process into paste.
  • Transfer to a bowl and mix in 60g sugar, 80g lard, and 60g honey. Stir thoroughly. The mixture will look loose and crumbly — this is normal.
  • Freeze for 30 minutes until semi-firm. Scoop into small portions (about 7–8g each) and roll into smooth balls. Freeze again for 10 minutes until fully firm. This prevents leaking when wrapping.
  • Note: Lard is essential for the lava effect. It solidifies when cold and melts into a flowing center when heated. Butter can substitute but will slightly change the flavor.

Step 2: Make the Dough (Hot-Water Method)

  • Place 400g glutinous rice flour in a bowl. Pour in 160g boiling water all at once and stir quickly with chopsticks until shaggy crumbs form. This hot-water step improves elasticity and prevents cracking.
  • Once slightly cooled, gradually add 140g cold water while mixing until no dry flour remains.
  • Knead into a smooth, soft dough. It may feel slightly sticky at first — that’s normal. Knead until smooth and pliable.
  • Note: Avoid adding extra flour unless absolutely necessary. Too much flour makes the skin tough.

Step 3: Wrap the Tangyuan

  • Knead the dough briefly again. Divide into equal portions (about 16–17g each). Roll into smooth balls.
  • Flatten one piece into a disc, keeping the center slightly thicker and edges thinner. Place a frozen filling ball in the center.
  • Carefully gather the edges upward, sealing tightly without trapping air. Pinch firmly to close and roll gently into a smooth ball.
  • Lightly dust with dry glutinous rice flour to prevent sticking. Repeat with remaining pieces.
  • Uncooked tangyuan can be frozen immediately for later use.
  • Note: Trapped air may cause splitting during cooking. Seal tightly and press firmly.

Step 4: Cook the Tangyuan

  • Bring a pot of water to a full boil. Gently drop the tangyuan in along the side of the pot. Stir gently to prevent sticking.
  • Cook over high heat. Stir 2–3 times before they float.
  • When all tangyuan float and slightly expand, they are fully cooked. Remove immediately.
  • Serve plain or in ginger brown sugar syrup or osmanthus honey syrup for extra flavor.
  • Note: Do not overcook. Prolonged boiling makes the skin overly soft.
