Bring the oil to a medium-high heat, about 1cm of oil. Peel and slice the plantains into 0.5cm in width. Cook the slices in batches for 2-3 minutes a side, until crisp and golden brown in colour. Place the cooked plantains onto some paper towel to drain off any excess oil. Season the cooked plantains with some salt before serving.
Chefs Tip: As it ripens, it becomes sweeter, and the peel turns black. If it gets too soft, it will just be a little messier to peel, but still safe to use. It must just be firm.
