Grind the leftover cooked rice into a smooth paste using a blender or a wet grinder.

In a bowl, combine the rice paste, rice flour, and the salt.

Gradually add water, little at a time, to form a soft, pliable dough, but not too soft, like you would for rotis.

Fill your idiyappam press with the dough.

Press the dough through the press directly into the idli moulds.

Steam for 10-12 minutes, or until cooked through...

Once cooked, take out the the idiyappam from the steamer and serve hot with your favourite chutney or sambar or stew.
