Boil potatoes, skin on, for ten minutes or until a knife can be pressed into the centre. Drain and set aside until cool enough to handle.
To make basil oil, combine all ingredients and blitz with a stick blender in a tall container until smooth and well combined. Check seasoning and set aside.
When cool enough to handle, cut the potatoes through the middle lengthways then remove a thin layer of skin from each outside to create a flat slice around 2cm thick.
Heat oil in a fry pan over medium heat then seal each side of the potato until crunchy and brown.
Remove potatoes and serve onto 2 plates, top with your remaining ingredients and drizzle with basil oil.
