Combine the flour, baking soda, and water in a bowl. Whisk until smooth to make a batter.
To Cook
Preheat the oil in the deep fryer to 350 degrees F (180 degrees C).
Cut the bananas in half longways, then in half short ways to get 4 even pieces per banana.Tip: Cutting the bananas at the last possible moment helps stop them from going brown, which can happen very quickly.
Dust the bananas in the flour.
Dip the flour dusted bananas in the batter, then gently place them into the oil in the Dutch oven.
Cook until the underside is lightly brown then roll to cook the other side, about 5 minutes per side. Cook in small batches so as to not cool the oil. When the second side is light brown, remove the banana fritter to a paper towel to rest.
Place on the serving plate then drizzle with the caramel sauce to serve.
