Place the chips into a pot of boiling salted water. Cook until firm (about 5 mins). Remove from the pot, drain well and place on a kitchen towel. Pat completley dry. Place in the fridge to let them cool completely.
Heat up the olive oil in a frying pan. When hot, add the cold chips and cook until golden. Once cooked, place the chips on more kitchen towel to drain out any excess oil.
Taking inspiration from the souvlaki bars of Athens, a jar of rigani-salt is a handy pre-mixed combination to have in the cupboard - for everything from these chips to grilled bread drizzled with olive oil. Simply mix around 100g good quality sea salt with 200g dried Greek rigani. Place in a clean jar, seal and leave in your cupboard.
