Eruca sativa

Eruca sativa, is an edible annual plant, commonly known as salad rocket,
rucola, rucoli, rugula, colewort, roquette, and arugula.

It is sometimes conflated with Diplotaxis tenuifolia, known as perennial wall rocket, another plant of the Brassicaceae family that is used in the same manner. Eruca sativa, which is widely popular as a salad vegetable, is a species of Eruca native to the Mediterranean region, from Morocco and Portugal in the west to Syria, Lebanon and Turkey in the east. The Latin adjective sativa in the plant's binomial is derived from satum, the supine of the verb sero, meaning "to sow", indicating that the seeds of the plant were sown in gardens. Eruca sativa differs from E. vesicaria in having early deciduous sepals. Some botanists consider it a subspecies of Eruca vesicaria: E. vesicaria subsp. sativa. Still others do not differentiate between the two.

Other common names include garden rocket, or more simply rocket (British, Australian, South African, Irish and New Zealand English), and eruca.The English common name, rocket, derives from the French roquette, a diminutive of the Latin word eruca, which designated an unspecified plant in the Brassicaceae family (probably a type of cabbage). Arugula, the common name now widespread in the United States, entered American English from non-standard (dialect) Italian. (The standard Italian word is rucola, a diminutive of the Latin "eruca"). The Oxford English Dictionary dates the first appearance of "arugula" in American English to a 1960 New York Times article by food editor and prolific cookbook writer Craig Claiborne.

Eruca sativa grows 20–100 centimetres (8–39 in) in height. The leaves are deeply pinnately lobed with four to ten small lateral lobes and a large terminal lobe. The flowers are 2–4 cm (0.8–1.6 in) in diameter, arranged in a corymb in typical Brassicaceae fashion; with creamy white petals veined with purple, and with yellow stamens; the sepals are shed soon after the flower opens. The fruit is a siliqua (pod) 12–35 millimetres (0.5–1.4 in) long with an apical beak, and containing several seeds (which are edible). The species has a chromosome number of 2n = 22.

In Italy, raw rocket is often added to pizzas just before the baking period ends or immediately afterwards, so that it will not wilt in the heat. It is also used cooked in Apulia, in Southern Italy, to make the pasta dish cavatiéddi, "in which large amounts of coarsely chopped rocket are added to pasta seasoned with a homemade reduced tomato sauce and pecorino", as well as in "many unpretentious recipes in which it is added, chopped, to sauces and cooked dishes" or in a sauce (made by frying it in olive oil and garlic) used a condiment for cold meats and fish. In the Slovenian Littoral, it is often combined with boiled potatoes, used in a soup, or served with the cheese burek, especially in the town of Koper. It is also used with salad, tomatoes and mozzarella cheese. In Rome, Italy rucola is used with special meat dish called straccietti that are thin slices of beef with raw rocket and Parmesan cheese.

A sweet, peppery digestive alcohol called rucolino is made from rocket on the island of Ischia in the Gulf of Naples. This liqueur is a local specialty enjoyed in small quantities following a meal in the same way as a limoncello or grappa.

In Brazil, where its use is widespread, rocket is eaten raw in salads. A popular combination is rocket mixed with mozzarella cheese (normally made out of buffalo milk) and sun-dried tomatoes.

In Cyprus, the plant is used in salads and omelets. An omelet with arugula (Greek rokka) is common in Cypriot restaurants.

In Egypt, the plant is commonly eaten raw as a side dish with many meals, with ful medames for breakfast, and regularly accompanies local seafood dishes.

In Turkey, similarly, the rocket is eaten raw as a side dish / salad with fish, but is additionally with a sauce of extra virgin olive oil and lemon juice.

In West Asia and Northern India, Eruca seeds are pressed to make taramira oil, used in pickling and (after aging to remove acridity) as a salad or cooking oil. The seed cake is also used as animal feed.
