To cut grapefruit into supremes: Slice off the top and bottom of the grapefruit. Stand fruit on one of the cut ends. Slice off the outer peel following the natural curve of the fruit, and removing the bitter white pith. Working over a bowl to catch all the juices, cut between each membrane to release segments.
Substitute hazelnuts for walnuts if desired.
