Vegetables
Needless to
say, raw or cooked, vegetables taste best when picked fresh and served
promptly. I can safely say that corn served and eaten within minutes of
harvesting is by far the best tasting! More and more people have taken to the
home garden or shop at farmers' markets for that reason. However, even if you
shop in a supermarket, vegetables are generally shipped and handled to ensure
that they retain as much flavor and nutrients as possible.
In
shopping for vegetables, pick those that are bright in color and crisp or
firm in texture. The healthy looking carrot, with its deep orange color, will
contain several times more vitamin A than the limp, pale one. The deeper the
color of the vegetable, the higher its vitamin A content will be.
When
it comes to root and stem vegetables, select the smaller ones; the bigger,
older ones are likely to be tough or woody and won't soften during
cooking.
Reject bruised and blemished vegetables, and any that have
cracks or tears, or have been chewed by insects; such damage makes it easy for
bacteria to enter the tissue.
After purchase, perishable
vegetables like leafy greens should not be washed until you are ready to use
them; this will minimize vitamin and mineral loss and curtail the growth of
bacteria. If the vegetables are dirty and need to be rinsed, shake them well,
wrap them in paper towels to absorb any excess moisture, and then place them in
plastic bags or in other closable containers before putting them in the
refrigerator.
Generally speaking, vegetables that easily wilt or dry out
should be kept in a dark, cool and slightly humid atmosphere. This restricts
the proliferation of bacteria and mold, prevents dehydration and suppresses
enzymes in the vegetables that, once activated, lead to loss of flavor and
texture and leads to decay. Spinach, broccoli, and celery are three of the many
vulnerable vegetables that will maintain their quality longer when refrigerated
at around 35 to 40 degrees and at high humidity. The vegetable crisper or
drawer in your refrigerator is a perfect environment for them.
Among the
hardier vegetables that should not be refrigerated due to the fact that their
starch converts to sugar are: potatoes, sweet potatoes, onions and winter
squash. All require cool, dark, well-ventilated conditions. That was the
well-founded premise of the root cellar! It prevented potatoes and other
veggies from sprouting, withering, or rotting. A cupboard on an outside wall,
away from the range or refrigerator, or a cool, airy basement provides today's
substitute.
When it comes to preparing and cooking vegetables,
you should rinse them under running water; scrub tough skinned veggies with a
vegetable brush. Trim sparingly: the green outer leaves of cabbage, for
example, are high in food value, and unless they are tough or wilted, these
leaves are well worth eating. Peel thinly if you feel it's necessary, or
consider leaving the skins on some veggies, such as potatoes. Nutrients are
directly beneath the skin and the peels are a good source of fiber and also
contain vitamins and minerals.
Slice or chop with a sharp knife. When
slicing, use a sawing motion; this will reduce bruising and further save
nutrients.
Avoid soaking sliced, chopped or peeled vegetables; soaking
leaches out minerals and water-soluble vitamins, especially if the pieces are
small. Also, try not to leave the vegetables exposed to air and light. Cook
them as soon as you can.
Generally speaking, vegetables need to be
cooked only until they are tender but still slightly crisp.
The most
misunderstood cooking method, unfortunately, is the one most commonly used:
boiling. When a lot of water is used and the process is prolonged, boiling can
destroy as much as 80% of the vitamin C, and cook and leach out other vitamins
and minerals as well. Too many well-meaning cooks throw away far more
nourishment than they realize when they pour the cooking water down the drain.
For example: an experiment proved that water in which cabbage was cooked
contained more B vitamins than the vegetable itself.
To conserve
nutrients and enhance flavor, most vegetables benefit from methods other than
boiling, such as...
Sautéed, Steamed & Waterless Cooked
Vegetables
These methods are a
sounder way to cook vegetables where nutrition is concerned.
Steamed
broccoli, for instance, retains 80% of its vitamin C - boiled broccoli, only
33%. The color is also better; the volatile acids in the vegetables rise with
the steam to the lid and then run down the sides of the pan into the water
below, and so they don't have any sustained contact.
To ensure that the
vegetables will cook evenly, distribute them loosely in the steamer; this
allows the vapor to circulate around them. A metal vegetable steamer or
steaming basket is a good investment but you can improvise with a colander or
strainer positioned over a saucepan.
Add the vegetables only after the
water is boiling; the high temperature helps to inactivate enzymes that would
otherwise destroy the vitamin C.
Sauteing and stir frying are two other
nutritionally sound methods. The trick is to cut or slice the vegetables small
or thin enough so that the heat can penetrate them quickly and to use the
smallest amount of oil possible (only a tablespoon or so will do) so as not to
elevate the calorie count unduly. Stirred and tossed over high heat in the few
minutes required to cook most vegetables by the saute or stir-fry method
surrenders little nutritional value.
A leafy vegetable such as spinach
-- which has a high moisture content -- will have enough water clinging to it
after rinsing to allow it to be cooked in a covered pot or pan without
additional water. With a tougher leafy vegetable like collard greens, a couple
of tablespoons of water will effectively aid the cooking
process.
Combinations of some vegetables are quite harmonious and
colorful. Try some combinations of those listed below. They need to be added in
accordance of how long they need to cook and how they are cut. These are in
order of when to add them:
· Radishes - cut into
rounds
· Carrots and beans - cut diagonally
· Celery - cut
diagonally
· Corn kernels
· Sprouts
· Potatoes -
quartered
· Turnips - quartered

chopped
· Rutabagas - diced
· Yams - cut into half
moons
· Parsley - minced
