Parangi Chekke, also known as Pineapple Chutney, is a popular South Indian dish made from fresh pineapple and a mix of spices. The origin of this dish is believed to be from the state of Karnataka in India.

To make Parangi Chekke, the following ingredients are typically used:

1. 1 large ripe pineapple, peeled and chopped
2. 1 cup grated coconut
3. 4-5 dried red chilies
4. 2 cloves garlic
5. 2 tsp jaggery (unrefined cane sugar)
6. Salt to taste

Here is the recipe for Parangi Chekke:

Blend the chopped pineapple, coconut, red chilies, garlic, jaggery, and salt into a smooth paste using a food processor or a blender.

Transfer the mixture to a saucepan and cook over medium heat until it thickens, about 10-15 minutes. Stir regularly to prevent burning.

Adjust the seasoning to taste. Add more salt or jaggery as needed.

Serve the Parangi Chekke as a condiment or dipping sauce with rice, idlis, dosas, or other Indian dishes.

In terms of preservatives, jaggery can help to preserve the chutney for a short period of time when stored in the refrigerator. However, it is best to consume the chutney within a few days to ensure maximum freshness and flavor.

This chutney is known for its sweet, tangy, and slightly spicy flavor and is a great addition to any Indian meal. The addition of coconut and garlic enhances the flavor and texture of the chutney, making it a delicious and unique condiment.
