roast sesame seeds till they pop and change color. when they have toasted well, remove them in a plate and keep aside. let the sesame seeds cool.

roast urad dal till they become light golden.
then add 2 dry red chilies (broken and seeds removed). you can use byadagi or kashmiri red chilies.
stirring often roast red chilies till they change color. this takes some seconds and by this time the urad dal will also turn golden and aromatic.

in a dry grinder jar or coffee grinder add the roasted urad dal and red chilies. also add a pinch of asafoetida.
grind to a semi fine or fine powder.
then add the roasted sesame seeds. using the pulse option for some seconds, grind the sesame seeds to a fine powder. you can also grind to a semi-fine powder. do make sure not to grind at a stretch. no oil should release from the ground sesame seeds powder.
add the sesame seeds powder to the cooked rice.
mix well. if there are any lumps in the rice, then break with spoon or spatula.
check the taste and if required, you can add some more salt at this step. mix well again. if using sea salt crystals, then grind the salt crystals with sesame seeds.
