Pulut tekan is just a plain glutinous rice cake. It is served with kaya (jam from pandan leaves) coconut jam. The glutinous rice cakes are coloured with bunga telang. Half-cooked glutinous rice is divided into two portions. Both are them added with coconut milk but one of them is added with the bunga telang juice.
This gives the rice cake a very bright blueish-indigo colour which is appealing to children. The half-cooked glutinous rice is then scooped in alternating fashion into the original tray to give it a marble effect of blue and white. The rice is then cooked some more and when it is cooked and cooled, it is cut into tall rectangles.
