Add 1 cup water to jaggery and melt it. Strain the jaggery and set aside to cool completely.
Take a bowl and add rice flour and wheat flour.
Add cardamom powder, salt and cumin powder.
Grind the banana till you get a smooth paste and mix it with the flour.
Add melted jaggery little by little till you get a pour able consistency or the consistency of idly batter. You may need around 1-1.5 cups of melted jaggery.
Heat the grated coconut with 2 tbsp ghee and
Add it into the unniyappam batter.
Finally add rava and mix everything together. Let the batter rest for 10 – 15 minutes. If the batter turns too thick after resting, add extra water to loosen it and stir well.
Meanwhile heat the unniyappam pan over medium heat and fill it with oil (upto half of each depression). When the oil gets hot, fill 3/4th of each depression with the batter (about 1 – 1.5 tbsp batter) and fry them at medium heat, uncovered.
Once the unniyappam is half-cooked, their sides will detach from the pan.When one side is cooked, flip over using a fork and fry until brown on both sides, about 2 – 4 minutes in total, over medium heat. If its browning too fast, reduce the flame to medium-low. Remove and drain onto a tissue paper to remove excess oil.
Serve warm or at room temperature.
