Italy has thousands of mile of coastline, with
innumerable habitats, and it consequently should come as no surprise that clams
and mussels play an extremely important part in the diet, beginning with
antipasti and carrying through to second course dishes, which vary from hearty
and earthy to supremely elegant. Broadly speaking, Italian clams and mussels
can be divided into two categories: Those sold live and those sold canned; in
selecting the latter you merely have to taste until you find brands you like
and stick with them. With live ones you have to be more careful. They're
generally sold by the bag, with the bag's being made of netting or otherwise
prepared so as to allow the animals to breathe, and the chances are that the
shells will be partially open as they sit on the shelf or bed of crushed ice or
what have you. If you shake the bag the bag gently, they should shut tight;
animals that fail to react when they're jogged are either dead or dying, and
you don't want either. Bend over and sniff the bag too; though shellfish do
smell slightly fishy, off or sharp odors are again a bad sign; select something
else.
Where you procure
your shellfish is also important: Clams and mussels are filter feeders, and if
their water contains pollution or harmful bacteria, so will they. Bari recently
suffered a cholera outbreak as a result of the sale of uncertified mussels, and
though you may not get something that serious no intestinal upset is fun.
Therefore, avoid roadside stands and people selling shellfish off the back of
trucks, and, if you decide to gather your own, check with the authorities to
make sure the area where you plan to gather is safe before you do. Larger
markets and reputable fishmongers will be a safer bet because they have much
more to lose from the sale of bad fish.
Once you get home
with your shellfish you will have to keep them alive until you're ready to cook
them; simply put them in their mesh bag on a damp towel in your refrigerator.
Assuming they were freshly caught they should stay alive for several days,
though you shouldn't take this as a license to buy ahead -- shellfish are best
when bought, taken home, and prepared; since the preparation does take a while
plan on enjoying them the day after you buy them. Why the preparation? Because
they're filter feeders and bottom dwellers, and therefore tend to be quite
sandy.
How to prepare
them: Fill a plastic bucket with water, adding one part non-iodized salt
for every ten parts water (by weight; this works out to 1 pound salt for every
10 pints water, or 500 g per every 5 liters, and let the water sit for several
hours to give the chlorine or other water-purification gasses it may contain
time to bubble out (treated water straight from the tap will kill what's put
into it). Scrub the clams well, or, if you're preparing mussels, scrape away
their beards with a knife and scrub them. Then soak the shellfish in the salted
water in the refrigerator for several hours, or overnight; during this time
they will purge themselves of sand and grit.
Having said all this,
what will you find in Italy? Mostly hard-shelled animals; the Mediterranean
doesn't really have anything akin to the soft-shelled clams one finds in North
America.
The clams you are
most likely to hear people mention are vongole veraci, which are known
as carpet shell clams in the English-speaking world (all name translations are
after Alan Davidson's wonderful Mediterranean Seafood, Penguin Cookery
Library, 1981). True vongole veraci are about 2 inches (5 cm) across, and you
will also find smaller, cheaper vongole that look similar, but are yellower --
vongole gialle, yellow carpet shell clams. To be frank, though you hear
a lot about the veraci, you more often encounter regular vongole.
They're eaten both raw and cooked.
Telline,
also known as Arselle, are known as wedge shells in the English-speaking
world, and live in the swash zone of sandy beaches. When I was little, I'd see
old men harvest them by dragging large strainers through the shallow water, but
they're no longer as common as they used to be. They're generally cooked, and
one often finds them with vongole in pasta sauce.
Cannolicchi, razor clams,
are shaped rather like the rectangular blade of an old-fashioned straight
razor, and are highly prized.
Datteri di
Mare, date shells, are highly prized both raw and in soups; their
popularity has put them on the endangered species list, and their sale is
illegal.
Cocciole or
Fasolari, cockles. Consumed both raw and cooked.
Cozze.
These are mussels, of the kind you'll see clinging in shiny black carpets to
any rocky surface that is bathed by the waves. Most Italian cozze are
commercially raised, and the Laguna Veneta is especially well known for its
cozze.
SO, NOW YOU'VE
GOT SOME. WHAT TO DO WITH THEM?
Eat them, of course.
The general Italian custom with live clams or mussels is to serve them
unshucked, so people can fish the shells out of the dish and suck away the
animal with a little of the sauce. Finger food, and very good too.
