Bring the water to a boil and remove ½ cup to a bowl. Add the rice to the remaining 1 ½ cups water, bring back to a boil and reduce the heat to a simmer.

Meanwhile, add the cocoa powder or chopped tablea to the hot water in the bowl. Mix to dissolve/melt and form a smooth paste. Add the mixture to the rice as it is cooking and mix through.

Continue to cook the rice, uncovered, at a steady simmer, stirring now and then until the rice is just about cooked through - it should take around 12-18 minutes from when the rice came to a boil.

Then, add in the sugar and mix to dissolve. Continue to cook for another 5 minutes to thicken slightly then remove from the heat and serve. Bear in mind that it will continue to thicken a little off the heat so you don't want it too thick when you remove from the heat.
