Here's what I did.
Ingredients :
100gm rice flour
50gm tapioca flour
50gm corn flour
1 tspn salt
130gm sugar
100ml blue pea flower water
500ml coconut milk
3 pcs pandanus leaf
Method :
(1) For blue pea flour water, place 30 blue pea flower into 140ml boiling water. Let it sit for 10 minutes then discharged the flowers.
(2) next, stir together 100ml blue pea water, pandan leaf and sugar, and cook over low heat till sugar dissolved. Discharged pandan leaf.
(5) now, stir flour mixture into coconut milk mixture in few batches till everything well cooperated.
(7) transfer batter into 7" greased baking tray lined with banana leaf, then brush the top with a layer of cooking oil.
(8) finally, bake at preheated air fryer 170'C for 20 minutes, after that 180'C for another 10 minutes. **Do take note that the tray should be place directly on fryer basket to bake.
Once it's done, leave cake to cool down completely before unmould it. Then slice cake with a plastic cutter, which is most appropriate.
