Seaweeds
One plant you should never overlook is
seaweed. It is a form of marine algae found on or near ocean
shores. There are also some edible freshwater varieties. Seaweed
is a valuable source of iodine, other minerals, and vitamin C.
Large quantities of seaweed in an unaccustomed stomach can produce
a severe laxative effect.
When gathering seaweeds for food, find
living plants attached to rocks or floating free. Seaweed washed
onshore any length of time may be spoiled or decayed. You can
dry freshly harvested seaweeds for later use.
Its preparation for eating depends on the
type of seaweed. You can dry thin and tender varieties in the
sun or over a fire until crisp. Crush and add these to soups
or broths. Boil thick, leathery seaweeds for a short time to
soften them. Eat them as a vegetable or with other foods. You
can eat some varieties raw after testing for edibility.
SEAWEEDS

Irish moss (Chondrus crispus)
Kelp (Alaria esculenta)
Laver (Porphyra species)
Mojaban (Sargassum fulvellum)
Sugar wrack (Laminaria saccharina)
Preparation of Plant Food
Although some plants or plant parts are
edible raw, you must cook others to be edible or palatable. Edible
means that a plant or food will provide you with necessary nutrients,
while palatable means that it actually is pleasing to eat. Many
wild plants are edible but barely palatable. It is a good idea
to learn to identify, prepare, and eat wild foods.
Methods used to improve the taste of plant
food include soaking, boiling, cooking, or leaching. Leaching
is done by crushing the food (for example, acorns), placing it
in a strainer, and pouring boiling water through it or immersing
it in running water.
Boil leaves, stems, and buds until tender,
changing the water, if necessary, to remove any bitterness.
Boil, bake, or roast tubers and roots.
Drying helps to remove caustic oxalates from some roots like
those in the Arum family.
Leach acorns in water, if necessary, to
remove the bitterness. Some nuts, such as chestnuts, are good
raw, but taste better roasted.
|
Steve's Notes: Acorns vary widely in their tannin
content. Some are almost edible raw, while others are too bitter
to eat even after boiling for hours. The larger acorns, from
oaks with more rounded leaves, seem to be the most palatable. |
You can eat many grains and seeds raw until
they mature. When hard or dry, you may have to boil or grind
them into meal or flour.
The sap from many trees, such as maples,
birches, walnuts, and sycamores, contains sugar. You may boil
these saps down to a syrup for sweetening. It takes about 35
liters of maple sap to make one liter of maple syrup!
|
Steve's Notes: It is too much effort to make syrup
in a wilderness survival situation. You can get a couple hundred
calories per day, however, by just drinking maple sap. In late
winter and early spring, collecting it can be as easy as snapping
off the ends of twigs and putting something there to catch the
dripping sap. I have collected a quart per day for several days
from one cut branch. |
