Cut the ends of your sweet plantain. Make a vertical line going down and peel. You can cut it into diagonal pieces, circles or long strips.
In a large pan add your oil and set to medium heat. Fry for about 3 minutes on each side or until you see a nice golden brown color. Remove from oil and drain over a paper towel to remove any excess oil. Serve and enjoy.
Notes
The riper your plantain the sweeter it will be. If your plantain is very sweet it tends to get brown faster when frying.
You can make these amarillos ahead of time and freeze until you are going to serve them.
