Peel and mash plantains well. Unless they are really overripe, they might be difficult to mash. Just put them in the food processor and they will mash easily and quickly.
In a large bowl, combine plantains with the chiles, scallions, salt, palm oil and egg. Mix well. Add flour and mix well.
In a large skillet, add enough oil for shallow frying.
Using a teaspoon, place a spoonful of batter into the oil for each fritter. Flatten it a little with the spoon and fry until golden brown on both sides.
Notes
Use wet hands to make it easier to form the pancakes.If you don't have palm oil, you can omit it. Use a pinch of ground turmeric to add the color.
