Boil the water, salt, and oil in a vessel with a lid.

Lower heat and add rice flour gradually, mixing continuously so that no lumps are formed.

Remove from heat and when cool, knead into a smooth dough.

Divide the dough equally into 9 balls.

Roll each ball out into a thin disc, put a small amount of coconut and jaggery in the centre and fold over into a crescent-shape pressing the end with a fork. Repeat till all are done.

Steam them in a steam cooker till done (insert a toothpick in the centre, if it comes out clean, the kozhukatta are done).
