Method
- 1
Extract the pandan. Blend the pandan pieces with 300 ml water until finely shredded, then pour through the sieve and press hard on the pulp. You should have about 300 ml of bright green juice; the leaves give both the colour and the vanilla-like scent.
- 2
Mix the green batter. Whisk the pandan juice with 100 ml water, 150 g sugar and the salt until the sugar has dissolved. Add 175 g rice flour and whisk until there are no lumps.
- 3
Mix the white batter. In the second bowl combine the coconut milk, 160 ml water, 150 g sugar and its salt, whisking until dissolved, then whisk in the remaining 175 g rice flour until silky.
- 4
Prepare the steamer. Oil the tin and bring the steamer water to a steady boil. Wrap the lid in the tea towel so condensation cannot drip onto the surface, and warm the tin inside for 2 min so the first layer sets evenly.
- 5
Build the stripes. Ladle in about 130 ml white batter, tilt the tin to level it and steam for 8-10 min, until it changes from opaque to translucent and feels set. Pour on about 130 ml green batter and steam another 8-10 min. Carry on alternating, giving each batter a stir first because the flour settles, until you have 6-8 layers; top up the steamer with boiling water when needed.
- 6
Steam the top layer. Give the final layer a longer 15-20 min so the whole block is firm and glossy right through.
- 7
Chill overnight. Let it cool completely, then refrigerate overnight, or at least 6 h. Glutinous rice starch firms as it cools, which is what lets you slice it cleanly.
- 8
Cut into squares. Loosen the edges with a knife, turn the block out and cut 16 squares with an oiled knife to stop it sticking.

Common mistake
A common mistake is pouring the next layer before the last is translucent; the colours then blur together, so wait for the change.
More from the cat
- Stir each batter before every pour, as the flour sinks quickly.
- Keep layers thin and even for neat stripes; a ladle that holds a set amount helps.
- Frozen pandan leaves work well; pandan flavouring is a fine substitute.
Storage
Keep covered at cool room temperature for up to 1 day, or in the fridge for up to 3 days. If it hardens in the fridge, steam the squares for 2-3 min to soften.
