Chopped grapefruit
Place the grapefruit on a chopping board and use a sharp knife to chop the fruit with the skin into halves, quarters or even smaller chunks. The skin can then be peeled easily for each individual piece.
Grapefruit segments
To get grapefruit segments, first peel the grapefruit by cutting a thin slice from both top and bottom. Then slice the peel and pith of the grapefruit starting from the top and moving your knife towards the bottom. Hold the fruit in one hand and cut along the inside of the membrane into the centre of the fruit to get V-shaped segments. Continue till you get all the segments from the grapefruit, and then discard the leftover middle membrane.
