Wash the radish under running water scraping the mud if any. Chop it in to 1" long strips. Keep it ready.
Next heat a cooking pan adding all the ingredients under list "To temper". Let the mustard seeds splutter and sizzle. Then add chopped radish, jaggery, turmeric powder and salt. Saute for while. Add half cup of water and let it cook.
When the radish is cooking, add coconut, mustard seeds, tamarind and red chilly to the mixer jar. Grind them together to coarse paste without adding water. Add this paste to cooked radish and mix thouroughly.
Radish stirfry is ready to serve with rice-rasam.
Notes
Do not add too much water to cook the radish pieces. Because this stirfry needs to be dry.
For more spice, increase the chillies or you can even add green chilly.
