Pour the oil into your chosen pot and turn the heat to high and leave to heat for about 10 minutes.
In the meantime cut the plantain on both ends and run the knife down the middle of the skin lengthways firmly but not too firm as to pierce through to the flesh. Then use fingers to peel off the the skin in one piece - it should be easy if you got the first step right. Watch the video below.
Now slice the plantain into your desired shape and toss with the salt.
When oil is ready add the plantain to the oil and turn heat down to medium high and leave to fry for about 5 minutes keeping an eye out and turning the heat down further if they are browning too fast. If you a deep frying use the tongs to push around the pieces in the oil and if shallow frying flip after 3-5 minutes on one side. After about 10 minutes they should be cooked and ready to go - enjoy!
