Dissolve the jaggery in the water and sieve it through cloth to remove any dissolved dirt
Crush the bananas and add to the jaggery
Add the flour and salt to this liquid mixture and mix well
Wash the paniyaram vessel well with water and dry it with a cloth
Place the vessel on medium flame on the stove and brush oil into each mold
Once the mold is hot add the batter and cover it with a lid
Once one side of the batter is cooked and has a golden colour, turn the white (wet) side facing down and cook without the lid. ( one can use a spoon to turn the sweet paniyaram over to cook on both sides)
Once both sides are cooked and have a golden colour, remove them from the mold and serve them hot.
