Remove skin from salmon and place in freezer for about an hour. On a utility slicer, slice diagonally across the grain (leaving the center bone) into paper-thin slices.
Arrange salmon slices in a flaky pattern on a platter. Sprinkle with a few basil leaves.
Stir through pepper, horseradish, a tiny bit of juice of a lemon, sugar, salt and oil. Pour over salmon and refrigerate with lid closed for one hour.
Garnish with remaining basil.
