Peel the bananas and wash them lightly. Cut the bananas into long, thin slices. Do not cut them too thick, they should be thin enough to cook easily from inside.
In a large bowl, add the gram flour, black pepper, cumin powder, salt, paprika, and turmeric powder.
Add water little by little and mix to form a smooth batter. The batter should not be too runny or too thick, just enough to coat the banana slices properly.
Heat the oil in frying pan on medium flame. Dip each banana slice into the batter and then gently drop it into the hot oil.
Keep the flame medium for the first 1–2 minutes so the batter sticks well to the bananas. Then lower the flame and cook for 2–3 minutes so the bananas cook well inside.
After 2–3 minutes, flip the fritters and cook the other side on low flame for another 2–3 minutes.
When they turn golden brown, remove them onto a kitchen towel to absorb extra oil.
Serve the banana fritters hot with chutney.
