provides a variety of important nutrients in one convenient package.
It has an ample supply of pectin, the soluble fibre that is effective
in lowering cholesterol levels, and of potassium, which is important
in controlling blood pressure. This familiar member of the citrus family
is even more highly valued as a source of vitamin C: These attributes,
along with its refreshing tart flavour, juicy texture, and low calorie
count, have made grapefruit a popular breakfast food.
probably developed from a cross between an orange and a shaddock, a
citrus fruit with thick skin, many seeds, almost no juice, and a very
sour taste. But skillful growers dramatically improved the flavour and
texture of grapefruit, beginning with the development of seedless varieties
nearly a century ago. The result is a citrus fruit that combines tanginess
to the West Indies, grapefruit became well established in Florida in
the early 1800s: Today, 80% of the U.S. crop and half of the world's
production is shipped from that state.
Since grapefruit is not picked until fully ripe, you never have to worry
about getting a "green" one. Under certain growing conditions,
the lemon yellow skin may revert to green after it is ripe, but the
fruit will lose none of its tangy sweetness.
Look for round, smooth fruits that are
heavy for their size (they will be juicy). Coarse-skinned grapefruits
or those that are puffy, soft, or pointed at one end are inferior; glossy
fruits with slightly flattened ends are preferable. Gray-brown "russeting"
or other skin defects are superficial and do not affect quality. At
room temperature, you may be able to detect a mildly sweet fragrance,
but it will not be apparent if the fruit is chilled.
Grapefruits can be left at room temperature for a week, and are juiciest
when slightly warm rather than chilled. For longer storage, they should
be held in the refrigerator , where they will keep for six to eight
weeks. Leave them at room temperature for a while before you juice them
or eat them.
Rinse grapefruits before cutting them. For serving from the "shell,"
halve grapefruit crosswise. Use a grapefruit spoon with a serrated tip
to scoop out the sections, or prepare the fruit using a sharp paring
knife or a curved-blade grapefruit knife, running it between each segment
of flesh and the membrane "dividers." (Grapefruits, like other
citrus fruits, may be called "seedless" if they contain no
more than five seeds, so don't be surprised if you have to remove a
You can also peel a grapefruit as you
would an orange; use your hands or pare the skin with a sharp knife:
Slice a disk of peel from the top, then pare slices downward around
the fruit; or, pare the skin in a spiral, as you would an apple. Then
pull apart the segments with your hands and, if desired, remove the
membranes from each segment.
