As one of the larger citrus species, the name grapefruit seems odd at first–that is until it is seen hanging in grape-like clusters from its tree branches. This hybrid was created by crossing a pomelo with a sweet orange, though by its color and size, it is evident that the pomelo is genetically dominant.
Although several varieties exist, the white-fleshed and seedless Marsh and the red-fleshed and seedless Redblush are two of the more popular North American sellers. Popular enough to warrant its own specialized knife (curved to follow the contour of the skin when carving out the flesh), the grapefruit is often enjoyed for breakfast but can also be sliced, broiled, and served as an amuse-bouche.
