Sea Lettuce
Known by the common name sea lettuce,
Ulva can
be eaten in salads or used in soups.
Ulva is
a particularly popular food in Scotland. Nutritionally,
it is very healthy.
U.
lactuca is made of 15% protein, 50% sugar and starch, less than 1%
fat, and 11% water when dried. It
is useful as roughage in the human digestive system.
Ulva are
very high in iron, as well as high in protein, iodine, aluminum, manganese
and nickel. They also contain
vitamin A, vitamin B1, vitamin C, sodium, potassium, magnesium, calcium,
soluble nitrogen, phosphorous, chloride, silicon, rubidium, strontium,
barium, radium, cobalt, boron and trace elements.
>In World War I, Lieutenant Colonel William
J. Phillipsen ate a salad of
U. lactuca, Enteromorpha and
Monostroma that
the Japanese call aonori. He
flavored it with salad cream, vinegar, lemon, pepper, onions and oil. Granted
there were a lot of ingredients other than seaweeds, but he described
it as wonderfully nice, slightly piquant and not inferior to the
best garden salad. An
eminent algologist named Savaugeaeau ate a similar salad without the
condiments and describes it as leathery and waxy in taste, and
in spite of a good digestion I thought I would be ill (Lee 214).
If you want to try the delicate alga for yourself, here are
some potentially tasty
Ulva recipes.
Most Ulva is harvested from wild populations,
but there are some cultivated sources as well. You
can store
Ulva in the fridge for 2-3 or freeze it for up to 6
months without losing the flavor. Ulva
may be air-dried or pressed into thin sheets. Drying
is best done in the sun, but ovens and even microwaves can do the job.
Ulva should
be thoroughly washed then soaked in water for a couple hours before use
(somebody says wash quickly, though try for yourself to find the
best way)
Ulva can
be toasted over a charcoal fire, broken up and addedto soups and sauces. Or
it can be used as fodder or animal feed.
Ulva is
usually processed before eating, but can also go fresh into salads.
Though not considered as much of a delicacy,
Ulva is
prepared and eaten the same as
Porphyra.
Ulva has also been used to treat burns.
