Turtle soup

China

In China, and in several countries with large populations of Chinese people, such as Singapore, turtle soup is a delicacy. The meat, skin and innards of the turtle are used in the soup. Soft-shelled turtles such as Pelodiscus sinensis are commonly consumed in this manner in Chinese cuisine, while consumption of hard-shelled turtles is often avoided due to their mythical connotations. However, the hard shells of certain turtles are used in the preparation of a dish called Guilinggao or "turtle jelly".

England

Turtle soup gained popularity in England in the 1750s but declined rapidly about 150 years later due to overfishing. According to food historian Janet Clarkson, the dish, which she calls out as one of several "noteworthy soups", became a symbol for civic dinners; she wrote, "From 1761 to 1825 it was never absent from the London Lord Mayor's Day Banquet. It is probably not unreasonable to hold several generations of aldermen and other civic leaders responsible for eating the turtle almost to exctinction."

Green turtle first became popular in England as "sea-tortoise" circa 1728: "Its Flesh is between that of Veal, and that of a Lobster, and is extremely pleasant.. They are frequently brought to England in Tubs of Sea Water, and will keep alive a long time." The earliest English recipes are for roast or boiled turtle, only later being used in a soup. About 1740–1750, it began to be widely imported to England, from Ascension Island or the West Indies. Samuel Birch is credited with being the first to serve turtle soup in London, spicing it with lemons and cayennes; it quickly became immensely popular, and as Lord Dudley has stated, "Of British soup, turtle always takes precedence in the list of honour". Giles Rose made turtle soup as follows: "Take your tortoises and cut off their heads and feet and boyl them in fair water, and when they are almost boyl'd, put to them some white wine, some sweet herbs, and a piece of bacon, and give them a brown in the frying pan with good butter, then lay upon your bread a-steeping in good strong broth, and well-seasoned; garnish the dish with green sparrow-grass and lemon over it." In Cookery and Domestic Economy (1862), the recipe begins as follows: take the turtle out of the water, turn it on its back, tie its feet, cut off its head. By about 1800, a good dinner portion was six pounds of turtle, live weight, and in London Tavern in August, 1808, 400 men ate 2,500 pounds of turtle in their dinner soup.

According to Clarkson, "It is difficult to overestimate the magnitude of the demand for turtles" during the period of the soup's popularity. As many as 15 thousand turtles were shipped live to Britain from the West Indies. Because of its popularity, the green turtle population plummeted from overhunting, and its cost rose correspondingly. As Isabella Beeton noted in 1861, "This is the most expensive soup brought to the table". Thus long before that time, mock turtle soup made from calf's head was widely adopted as a more economical substitute and became popular in its own right, with the two dishes sometimes being served at the same banquet.

United States

In the United States, the common snapping turtle has long been the principal species used for turtle soup. In this case the soup is also referred to as snapper turtle soup, or simply snapper soup (not to be confused with red snapper soup, which is made from the fish red snapper). It is a heavy, brown soup with an appearance similar to thick meat gravy.

In Philadelphia and the Delaware Valley, snapper turtle soup is an established part of Philadelphia cuisine. The famed seafood restaurant Old Original Bookbinder's, is known for its soups, including snapper soup; a canned version is also sold in grocery stores.

Turtle soup (and other dishes from turtle meat) are still served by a few restaurants in Minnesota, mostly on Fridays during Lent. It is said that it is primarily older customers who have previously eaten turtle who order the turtle dishes; younger diners are much less interested.

Among Creole communities, turtle soup is known as Caouane. In New Orleans, it is a specialty of several neighborhood and classic Creole restaurants such as Commander's Palace, Brennan's, and Galatoire's.

Turtle soup was the 27th U.S. President William Howard Taft's favorite food. He brought a chef who specialized in the dish with him into the White House for the specific purpose of preparing this soup.

Poisoning

Eating the flesh of some marine turtles can cause a type of rare, but possibly lethal food poisoning called chelonitoxism.
