Serve pineapple menaskai hot / warm with plain Rice / roti / dosa / Idli .
You can substitute pineapple with raw mango / Hog plum/ dry raisins / bitter gourd / ladies finger/ Capsicum / orange peels. But for ladies finger ,bitter gourd n orange peels u ve to roast it well initially n also increase tamarind quantity. Masala and rest of the things remains same.
* The tip of adding raw coconut oil while boiling , i got it from a cook who is a regular in my home for all functions. He was right ,It takes it to a new level.Actually ,he adds more than a tbsp but atleast to go near to that taste i add just a tbsp. If you want you can increase the qty or omit it completely.
Another tip , the cook gave me was to boil this gravy well in a low flame. The more you boil the more tasty it becomes .The consistency also thickens. Boiling it well also increases its shelf life. It does not spoil for a week if refrigerated and stays good without fridge for 2 days.
Basically menaskai will be tangy ,sweet n spicy. So to get the authentic taste add more jaggery , tamarind n chilli. But you can vary it depending on your pref.
