General & HistoryLooking at a palm tree it's hard to imagine that it descends from a magnolia, or that it is in any way related to a lily, but both are true. It is this very ability for rapid and extreme change that enabled the magnolias to dominate the world, as they do today. Palms are tropical and subtropical trees of great economic and culinary importance wherever they grow. In California, the Middle East and Southwest Asia the drought tolerant Date Palm is important for its sweet fruit. In the moister tropics the Coconut Palm and Toddy Palm provide the oil, sugar, fruit, timber, medicinals and roofing thatch the people depend on for sustenance and shelter. There is no part of a palm tree that isn't useful - and used. Palms come in three basic appearances:
VarietiesAçai Palm -
[Euterpe edulis, Euterpe oleracea]
E. edulis is a single stem palm so harvesting the heart kills the
whole tree.
Plantations must be completely replanted after harvest.
Açai fruit has long been an important food for inhabitants of the Amazon Basin, though the purple or green fruit is small and the flesh thin. Açai juice is often used as beverage and ice cream flavorings and for similar purposes. The juice is highly perishable so is generally marketed in frozen or dried form. Recently beverages containing açai juice have been marketed through
health food emporiums for their antioxidant content and anti-cancer activity.
The antioxidant content of these beverages is generally lower than in red
wine or grape juice and the anti-cancer properties are still under study.

Areca Palm - [Areca Nut Palm,
Betel Nut Palm, Areca catechu]
The fruit kernel of this smooth stemmed feather palm is the source of the nut used in betel nut chews. The photo specimens were purchased from an Asian market in Los Angeles and are just beginning to ripen. The seed kernel is still soft and hasn't yet developed red pigments. In general some slices of areca nut are mixed with lime (calcium hydroxide) and rolled up in a leaf of the betel vine (Piper betle). Various spices and tobacco are often included. This concoction (Paan in India) is then chewed for a mildly narcotic (and slightly addictive) effect. Use is common in Pakistan, India, Sri Lanka, Southeast Asia on into the Pacific Islands and north to Taiwan. Chewing betel nut stains the mouth red and relates to an elevated incidence
of mouth cancer. Its use is most prevalent in India and has been declining
in Southeast Asia but increasing somewhat in the Pacific Islands. It remains
very popular in Taiwan where it is peddled by scantily clad "Betel Beauties"
from neon lit one room glass paneled shops.
Coconut Palm - [Cocos nucifera]
Date Palm - [Phoenix dactylifera]
Doum Palm - [Thebaica,
Hyphaene thebaica]
Hearts of Palm - [Palmito, Palm
Cabbage].
While France is still the largest importer, hearts of palm are becoming
popular in the US for salads and appetizers. Most imported into the US are
from Peach Palms grown in Costa Rica.
Microwave Palm - [Cell Palm]
This North American feather palm, native to Los Angeles,
California, grows to maturity very quickly and then seems to just stops
growing. It is easy to identify from it's smooth brown trunk and unique
inflorescence. The photo specimen, about 60 feet tall, is in full bloom.
These palms seem never to produce mature fruit so their means of
propagation is somewhat of a mystery.
Nipa Palm - [Mangrove Palm,
Nipa (Philippines), Nipah (Indonesia, Malaysia), Dura Nuroc (Viet),
Gol Pata (Bangladesh), Dani (Burma), Attap Palm (Singapore),
Nypa fruticans]
This Southeast Asian feather palm grows in tidal mangrove swamps where it may constitute most of the vegetation. The trunk lies horizontal buried in mud and only fronds and flower stalks grow upward out of the mud and water (as in the photo). Sap from the inflorescence (flower clusters) can be tapped just as in other palms and is made into an alcoholic beverage called Tuba. In the Philippines Tuba is given a secondary fermentation to turn it
into vinegar called Sukang Paombong. Details and Cooking.

Oil Palm - [Elaeis oleifera
(Central and South America), Elaeis guineensis (West Africa) also
American oil palm, Attalea maripa (not much used)]
Palm oil is much used in cuisines of Central and South America, particularly Brazil, and Southeast Asia, and of course Africa. Southern India uses a lot of palm oil but gets theirs from coconut palms. Palm oil for cooking is easily recognizable by it's orange-red color. The fruit provides two types of oil, palm oil from the fruit pulp, used
mainly for cooking, and palm kernel oil from the kernel, used mainly for soap
and cosmetics. Palm oil has been proposed and somewhat used as a biofuel, but
ecological and economic factors need to be considered - the food vs. motor
fuel problem again.

species]
The flower clusters, which are boiled briefly before eating, have been
compared to asparagus in taste and texture, however that is just plain
wrong - they most resemble, in color, appearance, taste, and texture, baby
corn. They can be served alone as a vegetable but often appear with scrambled
eggs or other dishes where they are lightly fried. Some complain that they
are very bitter, but in my experience they are no more bitter than baby
corn.
Details and Cooking.
Palmetto - [Cabbage Palm,
Sabal palmetto]
Peach Palms - [Pewa (Trinidad and
Tobago); Pejibaye (Costa Rica, Nicaragua); Chontaduro (Colombia, Ecuador);
(and many more); Bactris gasipaes, Guilielma gasipae and
other synonyms]
Native to tropical forests of South and Central America, the fruit of this feather palm has long been consumed by native populations raw or stewed. Today it is often made into jams and jellies, dried and ground into flour or squeezed for oil. This palm is used for production of Hearts of Palm
because it is not killed by harvesting but rather sends up several new shoots.
It also has the desirable characteristic that the hearts do not discolor
when cut. Peach palms need less water than Açai Palms
so are more widely planted. Costa Rica is now the main supplier of hearts
of palm to the US, but Hawaii produces larger hearts and some production
has been started in Florida. Photo by USDA = public domain
. Rattan Palm - [Raffia Palm, Family Arecaceae
Subfamily Calamoideae Tribe Calameae - some 600 species]
While most familiar as material for casual furniture, the hearts of some
species are also harvested as food, available packed in brine in jars at
markets serving Southeast Asian communities. They look and taste
much like the more common Hearts of Palm but are much
smaller, tend to be more fibrous and may have a faint bitterness.

Medizinal-Pflanzen - copyright expired. The white
flesh has an apple-like consistency and a sweet tart flavor, The fruit of
salak pondo is dry, almost crumbly with a distinctive aroma, and is
not popular outside the region of growth. The fruit of salak bali
is juicier with a flavor likened to a diluted mix of pineapple and lemon
juice. It is popular with both natives and outsiders but is grown only on
the island of Bali.

Saw Palmetto -
[Serenoa repens alt. Sabal serrulata]
Toddy Palm / Sugar Palm -
[Palmyra Palm, Wine Palm, genus Borassus; Fishtail Palm, Sago Palm,
Caryota Urens (and similar); Sugar Palm, Arenga Palm, Black-fiber
Palm, Gomuti Palm, Aren, Irok, Kaong, Arenga Pinnata alt
Arenga saccharifera; Silver Date Palm, Sugar Date Palm
Phoenix sylvestris; Coconut Palm, Cocos nucifera]
Naming here is very confused - there are a number of very different trees under each or both of these names depending on region and plantation or who's talking about it. I've seen a number of articles with a picture of one species attached to the scientific name of another. In all cases the flower sepals are are tapped for a sap very high in sugars. The sap gathered will naturally ferment and become alcoholic within a few hours of sunrise. This fermented sap, toddy, is popular with the locals as gathered, and is distilled into a liquor for export. If the gathering vessel is coated inside with lime juice the sap will not ferment. It is then called "sweet toddy" and has a number of uses. It can be made into non-alcoholic drinks which are sold worldwide and made into sugar cakes which can be found in Indian and Southeast Asian markets. This is a light, tasty sugar and more nutritious than cane sugar - definitely my favorite sugar. The immature fruits of some of these palms are also used in various ways.
They are available in cans and jars in Southeast Asian markets in the US.
Young shoots are also eaten in the areas where these palms grow in abundance.
Wax Palms - [Carnauba Palm,
Copernicia prunifera; Caranday Wax Palm, Copernicia alba]
Aside from its well known use in auto polishes and leather goods,
carnauba wax is used to make candy corn shiny, as a mold release, wax
coating on fruit, and in many processed foods, confections and candies. It
is also used as a stabilizer in various munitions and explosives to keep
them from going boom until you want them to.
