Cook rice as you would normally either using a rice cooker or in a saucepan. Once it is done, spread the hot rice on a large serving plate and allow it to cool. Cooling the rice will allow the rice to be fluffy rather than clumpy at the end.
Prep the spice mix
Using a small blender, make a fine paste of all the ingredients for the spice mix - fresh coconut, red chillies, tamarind paste, and mustard seeds. Use as little water as possible at this stage.
Make the Vaggarnae
Heat the oil in a wide saucepan or kadai. Add mustard seeds and cover the pan. After the mustard seeds pop, remove the lid and add chana dal and urad dal. When the dals are a golden brown, add asafoetida (hing), curry leaves, and turmeric. This type of building a seasoning is called Vaggarnae. Add the spice mix to the vaggarnae.
Cook the mix for about 10 minutes on a medium flame until the oil begins to separate. You can store the cooked spice mix and Vaggarnae in the refrigerator for up to 3 days.
Assemble the chitranna
In a separate saucepan toast the peanuts in 1 tablespoon of oil. Add the cooked spice mix, peanuts and salt to the rice. Since the red chillies can be very spicy depending on the variety, I like to reserve some of the mix at this time.
Toss well and check the salt and spice level. Add the rest of the spice mix if needed at this point and toss again. Serve hot.
Notes
Serve with raita and papad as the rice course.
The spice mix can be made ahead and stored in the refrigerator for up to 3 days, or in the freezer for several months.
Look up the post on making Vaggarnae in the cooking techniques section for more information on making the vaggarnae correctly.
You can substitute the peanuts with roasted cashews for an extra luxurious touch to the dish.
