ขนมเทียนแก้ว: Crystal-Glazed Thai Dumplings (Easy Recipe for Home Cooks)

Introduction

ขนมเทียนแก้ว is a delicate Thai dessert known for its glossy, translucent skin and sweet, fragrant filling. Perfect for beginners, this recipe uses simple pantry ingredients—tapioca starch, glutinous rice flour, and sweet mung bean filling—to create small, glass-like dumplings that are steamed until beautifully clear. In this post you’ll learn how to make ขนมเทียนแก้ว step-by-step with tips to ensure smooth dough and perfectly steamed results.

Ingredients

• For the filling:
  • 1 cup split yellow mung beans (mung dal), soaked 1 hour and drained
  • 3/4 cup grated fresh coconut or desiccated coconut (if fresh unavailable)
  • 1/2 cup palm sugar or brown sugar, adjusted to taste
  • 1/4 teaspoon salt
  • 1 tablespoon coconut oil (for frying the filling)
• For the dough (outer skin):
  • 1 cup tapioca starch (also called tapioca flour)
  • 1/2 cup glutinous rice flour
  • 3/4 to 1 cup boiling water (adjust as needed)
  • 2 tablespoons sugar (optional, for slightly sweet skin)
  • 1/4 teaspoon salt
  • 1–2 teaspoons pandan extract or a few drops of green food coloring (optional, for color and aroma)
• For finishing:
  • Banana leaves or silicone cupcake liners (optional) for steaming cups
  • Coconut oil or neutral oil for brushing

Instructions

1. Make the filling: In a pot, cook the soaked mung beans with enough water to cover until soft (about 20–30 minutes). Drain any excess water and mash or blend the beans to a smooth paste.
2. Sauté the paste: Heat 1 tablespoon coconut oil in a pan over medium heat. Add the mashed mung beans, grated coconut, palm sugar, and salt. Stir continuously until the mixture thickens and becomes dry enough to form small balls (about 8–12 minutes). Remove from heat and let cool.
3. Divide the cooled filling: Roll the filling into small balls about 1 inch (2–3 cm) each. Set aside on a plate.
4. Prepare the dough: In a large bowl, mix tapioca starch, glutinous rice flour, sugar, and salt. If using pandan, add pandan extract. Carefully pour in boiling water in stages while stirring with a wooden spoon until the mixture comes together into a slightly sticky dough. Let it cool until comfortable to handle.
5. Knead and portion the dough: Lightly oil your hands and knead the dough briefly until smooth. Divide into equal portions (about 20 pieces depending on desired size). Roll each portion into a thin disk in your palm.
6. Assemble the dumplings: Place a mung bean ball in the center of a dough disk. Gently wrap the dough around the filling, sealing the edges and shaping into a smooth ball. Make sure there are no cracks; press edges together tightly.
7. Prepare steamer: Line a steamer basket with banana leaf squares or silicone liners to prevent sticking. Place each dumpling on the liner with some space between them.
8. Steam until translucent: Steam the assembled ขนมเทียนแก้ว over high heat for 12–18 minutes, depending on size. The outer skin should turn glossy and translucent. Avoid over-steaming to prevent the skin from becoming overly soft.
9. Finish and glaze: Remove from steamer and brush lightly with coconut oil to add shine and prevent sticking. Let cool slightly before serving—these are best enjoyed warm or at room temperature.
10. Storage: Store leftovers in an airtight container in the refrigerator for 2–3 days. Reheat gently by steaming for a few minutes to restore translucency.

Cooking Tips

These practical tips will help beginners succeed with ขนมเทียนแก้ว:

• If the dough cracks while wrapping, dampen your fingers with a little water and press gently to seal; you can also press a small patch of extra dough over cracks and smooth it.
• Adjust water gradually when mixing the dough—tapioca absorbs differently by brand and humidity. The dough should be soft and slightly springy, not dry.
• To make even-sized dumplings, weigh portions or use a melon baller/scoop for the filling and dough portions.
• Banana leaves add aroma and help steam evenly, but silicone liners or small parchment cups work well for home kitchens.
• Avoid stacking the dumplings in the steamer; leave space for steam circulation so each ขนมเทียนแก้ว becomes uniformly translucent.
• For flavor variations, try adding a little grated coconut to the filling, or a touch of vanilla or orange zest for a twist.
