In a deep kadai / pot , heat 2 1/2 cup water into luke warm . Prefer not to use any steel kadai /pot to cook ragi . Use a deep vessel ,as there are chances of ragi flour spilling when it comes to boil . Also use wider vessel , it becomes easier to stir ragi flour.
When water is luke warm , add 1/4 cup of flour and stir well.
Add 1/2 Tsp salt and 1 Tsp oil / ghee. This is optional , If you are making ragi balls for first time , then I would recommend you to use. Adding oil and salt avoids formation of lumps.
On a medium high heat , bring it to boil for about 8-10 minutes. Stir in between at 2-3 intervals. This is important step , only if ragi flour is well boiled only then lump free ragi balls can be made.
By end of 8-10 minutes , ragi flour starts to thicken slightly . Don't wait more than 10 minutes for ragi flour to thicken , even if its not thicken don't worry, proceed to next step. Cooking 1/4 cup of ragi flour in 2 1/2 cup water for 10 minutes is sufficient .
Now reduce heat or put on simmer , add 3/4 cup of ragi flour.
With a long handle wooden spatula or any spatula with long handle , quickly stir the flour in both clockwise as well as anticlockwise direction. Make sure flour is mixed well without any lumps. Stirring in both the directions , avoids formation of small lumps and breaks it if any.
Close lid and now cook on low medium heat for 5 minutes.
After 5 minutes , open lid and check ragi mudde . Wet you palm with water and touch ragi mudde in your fingers. It will not be sticky and can easily make balls from it. You can test this by pinching a small amount of ragi ball between your fingers and make a small ball.
Take ragi mudde kadai / pot off the stove , and briskly stir well everything in all direction.
Take a mudde plate or any plate , wet it . Place some ragi mudde on wet plate and with help of wet plams shape into balls of desired size. Approximately , it will be slightly bigger than the size of tennis ball. Alternatively you can also shape ragi mudde with the help of any wet bowl. Place ragi mudde in a bowl , swril it and shape into balls with help of your hands. Wet plams before making balls.
Once done serve ragi mudde with any spicy curry like mutton kheema curry , chicken curry , egg curry, masidda soppu saaru or bas saaru.
