Banh tam khoai mi (silkworm cassava cake)

Bánh Tằm Khoai Mì, also known as Silkworm Cassava Cake, is a traditional Vietnamese dessert made with grated cassava (tapioca) and coconut milk. Its unique name comes from its appearance — the cake is shaped like the silkworm, and it has a soft, chewy texture with a rich coconut flavor. The cake is often served as a sweet treat or snack and is popular in many Vietnamese households. The natural sweetness of the cassava is complemented by the creamy coconut, making it a comforting and satisfying dessert.

Ingredients:

  • 500g fresh cassava (tapioca), peeled and grated
  • 200g sugar (adjust to taste)
  • 1/2 tsp salt
  • 200ml coconut milk
  • 1/2 tsp vanilla extract (optional)
  • 1 tbsp tapioca starch or corn starch (optional, for firmer texture)
  • 1-2 tbsp toasted sesame seeds or roasted peanuts (for garnish, optional)
  • Banana leaves or parchment paper (for wrapping)

Directions:

  1. Prepare the Cassava:
    • Peel the cassava and grate it finely using a box grater or a food processor. If using fresh cassava, be sure to remove the hard, woody center and the brown skin.
    • Once grated, rinse the cassava under cold water to remove excess starch, then squeeze out any excess water to prevent the mixture from being too runny.
  2. Make the Dough:
    • In a large mixing bowl, combine the grated cassava, sugar, salt, and optional tapioca starch (for added firmness). Mix well to ensure the sugar dissolves evenly.
    • Gradually add the coconut milk to the cassava mixture, stirring continuously. If you like, you can add a little vanilla extract for extra flavor.
  3. Prepare the Steaming Setup:
    • Cut banana leaves into small squares or prepare parchment paper to line the steaming trays. This will help prevent the cassava cake from sticking during steaming.
    • Arrange the leaves or parchment paper in small cups or molds, ready for steaming.
  4. Steam the Cake:
    • Spoon the cassava mixture into the prepared cups or molds, pressing it down lightly to pack it evenly.
    • Steam the cakes in a steamer over medium heat for about 30-40 minutes or until the mixture becomes firm and translucent. Check the cakes occasionally to ensure they don’t overcook.
  5. Cool and Serve:
    • Once cooked, remove the cakes from the steamer and let them cool slightly. The texture should be soft and chewy.
    • Optionally, garnish with toasted sesame seeds or crushed roasted peanuts for added flavor and texture.
  6. Serve:
    • Serve the Bánh Tằm Khoai Mì warm or at room temperature. The cakes can be enjoyed as a sweet snack or dessert.

Optional Variations:

  • You can add a little pandan extract to the batter for a subtle green color and extra fragrance.
  • Some versions of this cake may include a small filling of mung bean paste or a dusting of shredded coconut on top.

Bánh Tằm Khoai Mì is a delightful dessert with a perfect balance of chewy, creamy, and sweet flavors, making it a beloved treat in Vietnamese cuisine!
