An Easy Kuih Recipe That’s Surely To Impress

To make this colourful and delicious Kuih, first prepare and cook glutinous rice to form the bottom lower layer. Start by soaking the glutinous rice for at least 4 hours or overnight. Soak one part with water and the other part with blue pea coloured water. Wash and then mix well the drained glutinous rice with coconut milk, salt and water.

Then steam over high heat till the glutinous rice turns soft and fluffy. Fluff and mix the glutinous rice till a marble effect is formed. Transfer onto an oiled pan and gently pressed down on the rice to really packed it. Then set aside while we worked on the upper custard layer.

Notes

  • Strain the purple sweet potato custard mixture to prevent any lumps. Otherwise this can create an uneven surface on the cake. 
  • When cooking the batter (top layer), stir continuously over low heat until the custard starts to thicken so that the cooked custard will not be too soft or mushy.Do not use high heat as it will make the custard lumpy and has a burnt taste if not careful.
  • Pour the thickened custard onto the glutinous rice while it is still hot and moist. Otherwise the two layers will not stick well. If the glutinous rice is already cooked but the custard is not yet ready, add a little water to the glutinous rice and continue to steam over low heat. This will keep the rice warm and moist. Also be sure to pour the custard mixture gently over the glutinous rice to prevent bubbles forming. The bubbles can also cause uneven surface.
  • The coconut milk for the glutinous rice must not be too much, just enough to cover the rice. Also should not be too thick. Otherwise it will affect the stickiness of the glutinous rice and both layers will not stick well.
  • To achieve a smooth surface for the kuih, we need to use low heat to slowly steam it. Leave a little gap on the steamer to allow steam to circulate so that the water does not drip back onto the kuih. Alternatively, can cover with cling wrap to prevent steam from dripping onto the surface.
