Place the salmon, skin-side up, on a chopping board and sprinkle with sea salt flakes. This helps crisp the skin.
Heat a little oil in a frying pan over medium-high heat. Cook salmon, skin-side down, for 4-5 minutes depending on thickness.
Turn and cook for 3-4 minutes. Test with a fork - if it flakes easily, it's ready. Salmon is best served a little pink in the centre.
