Firstly, heat a pressure cooker on moderate flame and add washed toor dal, chopped beetroot, turmeric powder, salt and water.
Then add little oil and cover the cooker lid.
Pressure cook this for 2 whistles and keep it aside.
Meanwhile prepare the masala for grinding. For that heat a small pan on medium flame and add oil.
When the oil is hot enough, add cumin, fenugreek seeds, chana dal, coriander seeds and urad dal.
Similarly add red chilli and black pepper.
Fry this for 1 or 2 minutes, and then curry leaves and grated coconut.
Again stir fry this for one more minute until dals & grated coconut turns to slightly golden color.
Now turn off the heat and transfer this to a blender.
Add little water and blend this to a fine paste. Keep it aside.
Further heat a pan and add ghee.
As the ghee starts to melt, add tempering ingredients like mustard, cumin, hing, red chilli and curry leaves.
Saute well for a minute until it splutters.
Next add the cooked lentil/dal and beetroot mixture carefully.
After that add salt, jaggery, tamarind juice, and blended masala.
Add little water if the sambar consistency is too thick.
Give a good mix and bring this to a boil for 4 to 5 mins on a low flame.
Then turn off the heat and add a tsp of coconut oil & this is optional.
Finally add chopped coriander leaves and give a quick mix.
Now the delicious Beetroot Sambar is ready to serve!
Enjoy this tasty sambar as a side dish with hot plain rice with a spoonful of ghee. It also goes well with roti or chapati.
