Heat a pan and add the mango puree. Cook for 2-3 minutes over low heat.
Add the ghee and a pinch of salt. Gradually add the rice flour while stirring continuously until it forms a soft dough.
Cover the dough and let it rest for 10-15 minutes. Once warm enough to handle, knead it into a smooth, crack-free dough.
In another pan, heat the ghee and add the grated coconut. Sauté for a minute.
Add the dates powder (or jaggery for children above 1 year) and cardamom powder. Cook until the mixture comes together. Allow it to cool completely.
Grease your palms with a little ghee. Take a small portion of the dough and flatten it into a small cup.
Place a spoonful of the coconut filling in the center and gently seal the edges to form a smooth ball or traditional kozhukattai shape.
Arrange the prepared kozhukattais in a greased steamer plate, leaving a little space between each.
Steam for 10-12 minutes or until the kozhukattais turn glossy and are cooked through.
Allow them to cool slightly before serving.
