Hard-Shell Crabs.
These are in the market all the year. They are sold alive and, also, like the lobster, boiled. Near the coast of the Southern and Middle States they are plenty and cheap, but in the interior and in the Eastern States they are quite expensive. They are not used as much as the lobster, because it is a great deal of trouble to take the meat from the shell.
Soft-Shell Crabs.
As the crab grows, a new, soft shell forms, and the old, hard one is shed. Thus comes the soft-shelled crab. In about three days the shell begins to harden again. In Maryland there are ponds for raising these crabs, so that now the supply is surer than in former years. Crabs are a great luxury, and very expensive. In the Eastern States they are found only in warm weather. They must always be cooked while alive. Frying and broiling are the modes of preparing.
Shrimp.
These are found on the Southern coasts; are much the shape of a lobster, but very small. They are used mostly for sauces to serve with fish. Their season is through the spring, summer and fall. There is a larger kind called big shrimp or prawns, sold boiled in the Southern markets. These are good for sauces or stews, and, in fact, can be used, in most cases, the same as lobster. But few shrimp are found in the Eastern or Western markets. The canned goods are, however, convenient and nice for sauces.
Terrapin.
This shell-fish comes from the South, Baltimore being the great terrapin market. It belongs to the turtle family. It is always sold alive, and is a very expensive fish, the diamond backs costing from one to two dollars apiece. Three varieties are found in the market, the diamond backs, little bulls and red fenders. The first named are considered marketable when they measure six inches across the back. They are then about three years old. The little bulls, or male fish, hardly ever measure more than five inches across the back. They are cheaper than diamond backs, but not so well flavored. The red fenders grow larger than the others, and are much cheaper, but their meat is coarse and of an inferior flavor. Terrapin are in the market all the year, but the best time to buy them is from November to February.
Oysters.
No other shell-fish is as highly prized as this. The oyster usually takes the name of the place where it is grown, because the quality and flavor depend very much upon the feeding grounds. The Blue-point, a small, round oyster from Long Island, is considered the finest in the market, and it costs about twice as much as the common oyster. Next comes the Wareham, thought by many quite equal to the Blue-point. It is a salt water oyster, and is, therefore, particularly good for serving raw. The Providence River oyster is large and well flavored, yet costs only about half as much as the Blue-point. The very large ones, however, sell at the same price. Oysters are found all along; the coast from Massachusetts to the Gulf of Mexico. Those taken from the cool Northern waters are the best. The sooner this shell-fish is used after being opened, the better. In the months of May, June, July and August, the oyster becomes soft and milky. It is not then very healthful or well flavored. The common-sized oysters are good for all purposes of cooking except broiling and frying, when the large are preferable. The very large ones are not served as frequently on the half shell as in former years, the Blue-point, or the small Wareham, having supplanted them.
