Like normal Idli dosa batter, the Mappila samba idli dosa batter is the same ratio 4:1. So today I am taking 2 cups of Mappilai samba rice and ½ cup of Urad dal(use the good quality urad dal) wash and rinse the rice and dal 2 to 3 times. Because unpolished rice has dust in it.
Once washed soak them separately. I soaked the Mappilai Samba Rice in one bowl and the urad dal and 1 tsp methi seeds in another bowl.
Let it soak for 5 to 8 hours. This rice needs more soaking time and here it is winter so I am soaking it overnight(complete 8 hours) and the next morning at 6 am I am Grinding the Idli batter.
Grind the urad dal + methi first with little water(approximately ⅓ cup to ½ cup). Don’t add water at a time and grind. Add water little by little and grind it. I ground the batter in Mixie and it required ⅓ cup + 3 tbsp water. Again the water quantity differs according to the urad dal quality so add water little by little and grind it. Transfer the ground urad dal batter in a bowl.
Add rice to the mixie jar, add ½ cup of water and grind it. Mappilai Samba rice takes a little more time to grind than the normal rice so grinds it in intervals. If you are using more quantity and grind it in batches. Grind it to a smooth paste, add a little more water if required. I have added ¾ of water to grind the rice.
Don’t add more water. Just add as much as required. Transfer the ground rice batter to the bowl which has urad dal batter, add 1 & ½ tsp salt and use your hand mix well.
Mix well so that the salt will dissolve and both the batter should combine.
Cover and leave it undisturbed for 8 hours, in a warm place and let it ferment.
Once fermented, mix the batter well and then drop the batter on idli mold and steam the idli for 15 mins or until it cooks.
Once idli is done, serve hot.
Super soft Mappilai Samba idlis are ready to serve.
