Take coconut, red chillies and mustard seeds in a mixer and grind coarsely.
After draining all the water, the rice flakes would have turned soft now. Next heat a pan with all the ingredients listed under "To temper". Saute and let them splutter. Next add peanuts.
Saute for 3 minutes so that peanuts turn crisp. Then add tamarind water, jaggery and turmeric powder.
Next salt and cook for 2 minutes. Then add ground coconut masala and continue cooking for few more seconds.
Next add drained rice flakes and mix gently. Ensure the individual grains are not broken.
