  1. 1

    Cut the water chestnuts into roughly 1 cm cubes. Cover them with water and add red food colouring (about 10 to 15 drops) until the water is bright red; leave them to soak.

  2. 2

    Make the syrup. one pandan leaf in the 1 1/2 cups of water for 10 minutes , then stir in the sugar until it dissolves. Add the rose water if using, then chill completely.

  3. 3

    Make the coconut milk. the coconut milk with the 1/4 cup of water, the salt and the second pandan leaf for 5 minutes , then chill.

  4. 4

    Bring a large pot of water to a and set a bowl of ice water beside it. Drain the chestnuts, then toss them with the tapioca starch about 2 tablespoons at a time until every piece is coated white and none stick together. Shake off the excess in a strainer.

  5. 5

    Cook the rubies in two batches. Scatter them into the rapidly water, stir briefly, and for 2 to 3 minutes (about a minute after they float). Dip a few into the ice water: the coating should settle into a clear gel. If many show white, uncooked starch, a minute longer. Move the batch to the ice water.

  6. 6

    Once cool, drain the rubies. Keep them at room temperature rather than in the fridge; they hold for the day.

  7. 7

    To serve, spoon rubies into bowls with ripe jackfruit (fresh or canned in syrup) or young coconut meat if using. Add syrup until it almost covers them, then a couple of tablespoons of coconut milk (about 2 parts syrup to 1 part coconut milk). Add crushed ice and stir until very cold.
