A classic Vietnamese sweet soup of Thai bananas simmered in a pandan-scented coconut broth, thickened with two types of tapioca. A great dessert for a cold winter's night.
Dissolve 10g salt in 1L cold water, add the peeled bananas, and soak for 5 minutes.
Drain the bananas and pat dry.
Place the bananas in a bowl with 50g caster sugar and toss gently to coat.
Rest for 30 minutes, turning once or twice, until the bananas release a little syrup.
Prepare the Tapioca
Place the small tapioca pearls in a saucepan of boiling water and gently simmer until clear.
Rinse the tapioca pearls with cold water to remove any excess starch.
Place the tapioca shreds in a bowl, cover with boiling water, and soak for 15 minutes.
Drain the tapioca shreds before adding to the coconut base.
Cook the Banana Coconut Base
Add the sugared bananas and any syrup from the bowl to a wide saucepan and cook over low heat for 5 to 8 minutes, gently turning, until they release liquid.
Continue cooking gently until the released liquid reduces slightly - the bananas should stay whole.
Add 600ml water and 200ml of the coconut milk, then add the tied pandan leaves.
Bring to a gentle simmer over medium-low heat and skim any foam from the surface.
Add 2g salt, then taste and add the optional 10g caster sugar if you want it slightly sweeter.
Simmer gently until the bananas are tender but still whole and holding their shape.
Remove the pandan leaves.
If the bananas become tender before the tapioca is ready, lift them out gently and set aside - return them at the end.
Finish with Tapioca and Coconut Milk
Add the drained tapioca pearls and tapioca shreds to the coconut base.
Simmer gently for 5 to 8 minutes, stirring often, until the tapioca pearls are mostly translucent and the shreds are soft.
Add the remaining 200ml coconut milk and return the bananas to the pot if you removed them earlier.
Stir gently and simmer for 2 to 3 minutes only.
Note: Do not boil hard β coconut milk can split and turn oily.
Turn off the heat and rest for 10 minutes before serving.
Assembly
Place one whole cooked banana into each small serving bowl and cut into pieces, or slice before adding for a cleaner presentation.
Ladle the warm coconut tapioca base over the banana.
Top with roasted crushed peanuts and serve warm, at room temperature, or chilled.
Notes
Substitutes:
Pandan leaves: frozen works fine. If unavailable, omit entirely β coconut, banana and peanut still carry the dessert. If using pandan extract or paste, start with ΒΌ tsp only; it intensifies quickly.
Bananas: sugar bananas or Thai bananas are preferred. Cavendish works β choose yellow with a few spots, not soft.
Tapioca shreds: if unavailable, use 80g small tapioca pearls total. Do not substitute noodles.
Sago pearls: can replace small tapioca pearls at the same weight; cook until mostly translucent.
