Grind together coconut and cumin seeds.
When the pineapple gets fully cooked, add the ground coconut mixture.
Allow the mixture to get cooked.

Heat oil in a pan.
Splutter mustard seeds, dry red pepper and curry leaves.
Add the above seasoning into the pineapple mixture.
Allow it to cool.
Add curd and stir it to get the reqd consistency.
:- You can add sugar, if you don't find it sweet. (Sometimes, the pineapple might not be sweet enough.)
