Dry roast moong dal for 3-4 minutes. Wash the dal 2-3 times and add 1 cup water. Pressure cook for 2 whistles.
Add 1 tsp ghee in kadai and fry the rava until nice aroma comes and turns to light golden color. Set aside.
In the same kadai add remaining ghee and add whole black pepper. When pepper starts to pop, add cashewnuts and fry until golden.
Then add jeera, curry leaves, ginger and fry few seconds. Add 3 cups of water, salt and bring to boil.
Once it comes to rolling boil, reduce the heat to low and gradually add rava and mix well. Cover and cook for 5-6 minutes or until rava is completely cooked.
Add the cooked moong dal and combine everything. Cook for 1-2 minutes and remove from heat.
Notes
For a low calorie pongal, you can either make it with half ghee and half oil or just with oil alone.
You can also add finely chopped green chillies for some spice.
The moong dal should not become too mushy. It should be cooked until soft
