Prepare all ingredients and keep them ready.

In a mixing bowl, combine rice flour, maida, baking soda, salt, turmeric powder, cardamom powder, and sugar to make the batter.

Stir well to combine all the ingredients.

Add little water at a time and make a thick batter that smoothly coats the back of a spoon.

Cut the banana into thin, long stripes and set aside.

Heat oil in a kadai (wok) for deep frying and keep it ready.

Dip the banana slices in the batter until well coated.

Carefully slide the battered banana slices into the hot oil.

Deep fry the Kerala Pazham Pori until golden brown and crisp on both sides.

Drain the Kerala Pazham Pori from the oil and place them on a kitchen paper napkin to drain excess oil.

Serve hot as a tea time snack or for Onam.
