Wash and clean the radish under running water. Peel the skin off and grate it using a fine grater. Also keep the onion ready by chopping it finely.

Take grated coconut and salt in mixer and grind to fine puree adding water as required. In a bowl whisk the yogurt and mix it with coconut puree.

Next in a pan heat cooking oil. Add mustard seeds followed by lentils and curry leaves. As the mustard seeds sizzle add chopped onion and saute for few minutes. As the onion turn translucent include grated radish and slit green chillies. Continue sauteing for few more minutes and switch off.

When the radish mixture cools down to room temperature combine it yogurt plus coconut mixture in the bowl. Very healthy and comforting radish raita is ready to serve with rice or paratha.

Sauteing radish along with onion helps to reduce the strong astringent flavors of radish.

If you like raita to be more spicy, instead of using slit green chillies grind it along with coconut.

Do not use sour yogurt which may turn the raita tangy. I would recommend fresh yogurt.
