Skin your plantains, do this by cutting the ends off, find one of the ribs and slice down it. You can use a spoon or your thumb to get under the skin and peel it all off. Slice your Plantains into about 1 inch sections on a slight angle.
On a medium/high heat you want to fry the Plantains for about 5ish minutes. If they are not fully submerged then flip them half way through. You just want them fried to soften them up.
Allow to cool a little so you don't burn yourself, you want to smash the Plantains down. There is a press for this but I don't have one. You can use the bottom of a plate, a spatula, or even your hand.
Take them bake to your oil and on a medium.high heat. Fry until they are a nice golden brown on both sides. Lightly salt and allow to cool and they are ready to serve.
