Clams
There are two basic varieties of clams – Hard Shell
Clams and Soft Shell. There are several sub-varieties based
primarily on where they grow as well as on the size of the
clam (clams are measured by the diameter of their shell).
The neck is the siphon through which clams collect nutrients
and soft shell clams have a longer neck than their hard shell
cousins. Because of this, the shell of soft shell clams can’t
close completely. Soft shell clams found in the Atlantic include
the ubiquitous steamer.
Other East Coast hard shell clams include (smallest to largest)
littleneck (<2 inches), cherrystone (a little bit larger
at about 2 1/2 inches) and the quahog, a.k.a the large or
chowder clam (3 inches or more).
The most notable west coast hard shell clams are the pismo.
These are found on (you guessed it) Pismo beach. Small butter
clams are found further north in the Puget Sound area are
small and very tender clams. Soft shells found on the west
coast include the razor clam (there is an east coast clam
called razor but this is not a true razor clam) and the geoduck
clam (pronounced gooeyduck). The latter is a large six inch
clam that can have a neck as long as two feet.
In the colder East Coast and Pacific Northwest waters, clams
are available year round. Further south on the West Coast,
the season ranges from November to April. When buying hard
shell clams, tap the shell and the clam should close. If it
doesn’t, it is dead. Soft shell clams should retract
and move a bit when the protruding neck is touched.
Fresh clams can be gritty. You can soak them in water with
a bit of cornmeal to help purge any grit inside the shell.
Make sure that you add a little salt to the water (clams are,
after all, saltwater animals). Use about 1/3 of a cup of salt
in a gallon of cool water. You don’t need much cornmeal – two
tablespoons or so. The clams will feed on the cornmeal and
expel the grit and such that are inside the shells.
For a chowders and soups any clam will do but I feel that
the smaller the clam the better. They are sweeter and give
the chowder a more delicate flavor. Cooking clams should be
done carefully over low heat to keep them from overcooking
and getting tough. They don’t take very long to cook
and just about the time the shell opens the clam is done.
