Delicacy in the context of Tuber melanosporum

Abalone (/ˈæbəloʊni/ or /ˌæbəˈloʊni/; via Spanish abulón, from Rumsen aulón) are sea snails in the genus Haliotis, the only genus in the family Haliotidae. Abalone shells are distinctive for their flattened, ear-like shape, nacreous interior, and row of holes used for respiration. The flesh of abalone is widely considered to be a delicacy, and is consumed raw or cooked by a variety of cuisines. Abalone are globally distributed, with approximately 70 known species alive today. Though some species are small, the largest abalone can attain a length of 300 millimetres (12 in).

Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters, are in the superfamily Ostreoidea.

Some species of oyster are commonly consumed and are regarded as a delicacy in some localities. Some types of pearl oysters are harvested for the pearl produced within the mantle. Others, such as the translucent windowpane oysters, are harvested for their shells.

Caviar or caviare is a food consisting of salt-cured roe of the family Acipenseridae. Caviar is considered a delicacy and is eaten as a garnish or spread. Traditionally, the term caviar refers only to roe from wild sturgeon in the Caspian Sea and Black Sea (beluga, ossetra and sevruga caviars). The term caviar can also describe the roe of other species of sturgeon or other fish such as paddlefish, salmon, steelhead, trout, lumpfish, whitefish, or carp.

The roe can be fresh (non-pasteurized) or pasteurized, which reduces its culinary and economic value.

Offal (/ˈɒfəl, ˈɔːfəl/), also called variety meats, pluck or organ meats, is the internal organs of a butchered animal. Offal may also refer to the by-products of milled grains, such as corn or wheat.

Some cultures strongly consider offal consumption to be taboo, while others use it as part of their everyday food, such as lunch meats, or, in many instances, as delicacies. Certain offal dishes—including foie gras and pâté—are often regarded as gourmet food in the culinary arts. Others remain part of traditional regional cuisine and are consumed especially during holidays; some examples are sweetbread, Jewish chopped liver, Scottish haggis, U.S. chitterlings, and Mexican menudo. Intestines are traditionally used as casing for sausages.

Kobe beef (神戸ビーフ, Kōbe bīfu) is Wagyu beef from the Tajima strain of Japanese Black cattle, raised in Japan's Hyōgo Prefecture around Kobe city, according to rules set out by the Kobe Beef Marketing and Distribution Promotion Association. The meat is a delicacy, valued for its flavour, tenderness and fatty, well-marbled texture. Kobe beef can be prepared as steak, sukiyaki, shabu-shabu, sashimi, and teppanyaki. Within Japan, Kobe is one of the three Sandai Wagyū, the "three big beefs", along with Matsusaka beef and Ōmi beef or Yonezawa beef.

Kobe beef is also called Kōbe-niku (神戸肉; "Kobe meat"), Kōbe-gyū or Kōbe-ushi (神戸牛; "Kobe cattle") in Japanese.

Edible bird's nests, also known as swallow nests (Chinese: 燕窝; pinyin: yànwō), are bird nests created from solidified saliva by edible-nest swiftlets, Indian swiftlets and other swiftlets of the genera Aerodramus, Hydrochous, Schoutedenapus and Collocalia, which are harvested for human consumption.

Swiftlet nests have been used as a delicacy for over 400 years, most often as soup. They are particularly prized in Chinese cuisine due to the rarity, high protein content and rich flavor, and are among the most expensive animal products consumed by humans, with prices up to about $4,300 per pound ($9,500/kg) depending on grading. The type or grading of a swiftlet nest depends on the bird species, as well as the shape and colour of the bird's nest. It is usually white in colour, but there also exists a red version that is sometimes called 'blood nest' (Chinese: 血燕; pinyin: Xuě Yàn). According to traditional Chinese medicine, it promotes good health, especially for the skin.

Foie gras (lit. 'fat liver'; French: [fwa ɡʁɑ] , English: /ˌfwɑːˈɡrɑː/ ) is a specialty food product made of the liver of a duck or goose. According to French law, foie gras is defined as the liver of a duck or goose fattened by gavage (force feeding).

Foie gras is a delicacy in French cuisine. Its flavour is rich, buttery, and delicate, unlike an ordinary duck or goose liver. It is sold whole or is prepared as mousse, parfait, or pâté, and may also be served as an accompaniment to another food item, such as steak. French law states, "Foie gras belongs to the protected cultural and gastronomical heritage of France."
