Usually I use these products to fry 4 bananas, but this depends on the amount of the mixture for frying.
Step 2: Preparation
Cut the bananas in circles. Mix the egg, the sugar, the salt and the baking soda. Then slowly add the flour while stir the other products. The mixture must be something like cake batter.
Step 3: Frying
Fill a frying pan with about 2 cm oil and wait until it gets warm. Carefully roll each banana circle in the mixture and then put it into the oil until it gets like "golden". Then turn the banana to fry on the other side. I fry them for about a minute or two on a gas stove.
