A suprême cut removes peel and pith from citrus fruit. First, slice a little off the top and bottom of the fruit. Trim away the skin and pith, starting at the top and following the curve of the fruit downwards. Cut away all of the skin and the white pith cleanly, avoid also taking the fruit. Trim any pith that you missed. Cut into each side of the segment, next to its connecting membrane, and remove fruit segment. Collect segments and juice in a bowl.
