Fry them in medium heat without using oil until it makes rattling sound.(after cooling you can keep this in air tight box in refrigerator for later use !!)Dont over fry it, because it will make the theeyal bitter
3. Grind the dry roasted coconut in a mixer to a fine paste .(tip: first grind it to very fine powder,-you will see the coconut producing oil and becoming wet and will stick to bowl's sides.now add 2-3 tbsp water and grind again-fine paste is ready)
4. Pour the tamarind juice to the fried shallots,add salt and boil.
5.Now add the ground coconut paste.Then wash out the bowl with 1/4 cup water and add this to the shallots.Cook/boil it for 2-3 minutes

Easy version
To make it more easier you can avoid the shallots frying step.Instead of frying you can 
1.Cut the shallots into 2-3 big pieces. 
2. Heat oil in a pot ,Splutter mustard seeds.Add red chillies and curry leaves.Then add the chopped shallots and saute until it is soft and almost fried -or you can fry it at this stage ;-)
3.Now add the tamarind juice, coconut paste and salt.Boil and cook.
Note :This theeyal is more of sweeter in taste, if you want a spicy one, adjust the red chilli powder while frying the coconut.or you can add green chillies while making it.
