Fresh
beans are classified into two basic categories: edible pod beans and shell beans.
Green beans, otherwise known as snap or string beans, are the most popular
edible pod bean in the United States. The lima bean is the most common
shell bean sold in the United States.
Edamame,
a shell bean, is also called an immature green soybean. The popularity of
this bean has grown in the past decade and is now easily found frozen in
most major supermarkets.

Edamame
Edamame
is of Chinese origin and was developed in Japan especially for eating out
of the pod. Edamame is a variation on the same yellow and black field
soybean that is transformed into many popular soy products such as tofu,
miso, and soymilk. However, because of its recent introduction into the
U.S. market, only a small percentage of U.S. soybean fields are devoted to
growing edamame.
Some call
edamame the super or wonder vegetable because it is the only vegetable that
contains all nine essential amino acids. This makes edamame a complete
protein source, similar to meat or eggs. Edamame also contains isoflavonoids. They are found in all soy products and
are being studied for their health benefits.
Availability: Edamame is
rarely sold fresh, but is available frozen all year.
Preparation: To eat beans
right out of the shell, boil them until they are al dente (still slightly
firm). Rinse to cool slightly, and season as desired. You can easily suck
the al dente beans out of the shell. Beans may also be shelled and added to
other dishes, such as salads. Beans are easy to shell after they are boiled
briefly.
Green
Beans
These
beans are often called string beans because years ago a fibrous string ran
along the seam of the bean. The string was noticeable when you snapped off
the ends. The snapping noise is the reason for its other nickname.
Availability: Fresh green
beans are available all year, with a peak season of May to October. Green
beans are also available canned and frozen.
Selection: It is best to
handpick green beans from a market that sells them loose. To ensure uniform
cooking time, select beans of similar size and shape. Choose slender beans
(no thicker than a pencil) that are crisp and free of blemishes. The beans
should be a bright green color. Do not purchase beans that are stiff or
have the seeds visible through the pod because those beans will be tough.
Storage: Keep green
beans dry in a perforated plastic bag in the refrigerator. They should stay
fresh for 4 to 5 days.
Preparation: Wash beans
thoroughly in clear, cool water. Beans can be cooked whole, cut crosswise
or diagonally, or French-cut (i.e., cut along the length of the bean). If
you want sweet tasting, crisp fresh beans, cut them as little as possible.
Cut older, more mature beans in the French style (i.e., lengthwise).
Stir-frying
is one of the easiest ways to prepare green beans. This method maintains
more nutrients than other cooking methods. Whatever cooking method you
choose, remember to cook beans as little as possible, using the least
amount of water possible.
Boiling,
steaming, and microwaving are other common methods for preparing green
beans. When boiling, beans may release some nutrients into the water, so
try to re-use the bean water to regain some of the nutrients lost. For
example, you can use the water to boil rice.
TIP: Green beans continue to
cook after you take them out of the boiling water. Either take them out
just before they are cooked the way you like, or plunge them into ice
water immediately to stop them cooking further.
|
TIP: The fewer beans in the
pan, the quicker they cook and the better they taste. If cooking more
than one pound at a time, use separate pans.

Lima
beans originated in Peru and have been grown there since 6000 B.C. The name
lima bean comes from the capital city of Peru, Lima. Lima beans are often
nicknamed chad beans or butter beans. In the southern part of the United
States, lima beans are almost always called butter beans, even in markets
and restaurants.
Varieties: Lima beans come
in three main varieties: large, small, and dwarf.
Large lima
beans are green or speckled. The speckled kind have a creamy texture and a
strong earthy flavor, unlike the pale green ones.
Small
lima beans are also called sieva beans and have
several other nicknames, such as Carolina bean, civet, seewee,
and sivvy. Most small limas
are pale green. Small limas are less starchy than
the larger varieties.
Dwarf
beans, also known as butter peas, are white and speckled and the least
starchy of the limas.
Availability: Fresh lima
beans are difficult to find in the United States, but can occasionally be
found at farmers markets. It is easier to find lima beans in the southern
United States than anywhere else in the country. Most lima beans are dried,
canned, or frozen.
Preparation: Fresh lima
beans need to be shelled before they are eaten. Shelling can be a little
tricky, especially with larger beans. Beans are easier to handle if they
are tender and have full pods. One method used for larger beans is to
simply cut open the pod with scissors and remove the beans by hand. To
remove the beans from smaller limas, pull off the
string along the seam, and press the two sides open to pop the beans out.
Rinse canned limas before using them to reduce
their gas-promoting properties.
Lima
beans should never be eaten raw (see warning below). The most common
methods of preparation are boiling and microwaving. Only a small amount of
water needs to be used for either method.
WARNING: Do not eat raw lima beans.
They contain linamarin (also called cyanogen), which releases a cyanide
compound when the seed coat is opened. Don’t worry; cooking deactivates
this compound. The United States sets regulations to restrict
commercially grown lima beans to those varieties with very low levels of
this linamarin, but lima beans grown elsewhere, may have 20 to 30 times
the concentration allowed in the United States.
