Wash the plantain and peel off the skin using a knife.
Chop the plantain into chunks and blend in a blender with the egg.
Or you can mash the plantain and egg in a bowl with a fork until a good blend is achieved Add flour, a dash of salt and pepper and the cinnamon.
Mix thoroughly with a fork until well incorporated.
Let the batter stand for about 10 minutes.
Heat the oil in a heavy-bottomed pot over medium heat.
Once the oil is hot (you can test it by adding a drip of batter into it and it should sizzle), scoop the batter with a cookie scoop and form a ball with your thumb and first index finger.
Drop the scoops of batter into the oil leaving space between them.
Fry the balls until golden brown all round.
Transfer to a paper-towel lined plate to drain excess oil.
