So add the ragi flour to a tall container. Add 2 cups of water so that the water level is about an inch above the flour. Stir and set aside. (1 cup finger millet flour +2 litre Water)
Stand the container untouched for say 60 minutes. The flour settles, and the husk is floating on top. Decant the water.Repeat this another 2 times. You will find that the flour is clearer.
Grease a 6-inch tray with ghee and set aside. (1 teaspoon Ghee)
In a thick-bottomed wok, cook the ragi flour, coconut milk, jaggery, salt, and cashew nuts on low flame. (200 ml Coconut milk+1 cup Jaggery+pinch Salt+10 Cashew Nuts)
Keep stirring the wok continuously so the mixture does not become lumpy or stick to the bottom until it thickens.
Transfer to the greased tray, level the top of the pudding. Cool.
Cut into slices and serve.

Notes
Please feel free to increase/reduce the amount of coconut milk used; you will get a thinner/thicker milk, and the contents will be less/richer.
You can also make the satv by soaking and grinding the nachni.
