Grapefruits are large, round citrus fruits with thick or thin peels that are removed to expose the juicy segmented fruit. The sweet-tart flesh is white or pink. The flesh of the Ruby Red variety has a dramatic deep pink hue. Fresh grapefruit is available year-round.
To peel and section a grapefruit:
Using a small knife, cut a thick slice of peel off the bottom and top. Remove the remaining peel in strips along with the white pith. Cut the sections free, letting them drop into a bowl to catch juices.For other citrus varieties, see blood oranges, lemons, limes, oranges, and tangerines.Grape juice is the sweet juice extracted from grapes, available bottled or as frozen concentrate.
