Using a sharp chef's knife, cut away the peel and the white part or pith from the grapefruit. Carefully cut inside the skin of each segment to remove each section of flesh. Squeeze the membranes over a bowl to extract all the juice. Whisk the honey and mint into the juice and set dressing aside.
Arrange the grapefruit segments on a platter or in a shallow bowl and drizzle with some of the dressing.
