Prep up: Make sure you use thick batter. Use clean grated or powdered jaggery free from dust and stones. If your jaggery is not clean, melt it with 1 to 2 tbsp water. Filter and boil until thick. Then cool it and use here.
Make the batter: Mix all the ingredients together to a thick batter.
Make sweet paniyaram: Grease the paniyaram pan and add few drops of oil/ghee in all the cavities. Heat up well until hot. Turn the flame to medium and fill ¾ of each cavity. Cover with a lid and cook.
When the base is set and firm, flip them to the other side with a skewer and cook until crisp & cooked thru. Poke a skewer or a fork to see if it is cooked inside. Serve sweet paniyaram hot or cold.
