[Arugula (North America, Australia); Rocket (England); Oruga, Arugula,
Rucula (Spanish); Rucola, Ruchetta (Italian); Roquette (French);
Eruca sativa (mustard family)]
This popular salad green of Mediterranean origin has been used since at least Roman times. Almost unknown in the U.S. a decade ago it is today the "must have" green for yuppie salads, so supermarkets stock pre-cut and washed bags of "baby" arugula. The leaves are small and tender but have a distinctly mustardy bite, backed by an unusually complex flavor.
Some varieties have leaves less deeply cut than the photo specimen and the leaves are very deeply cut on the wild version. In Italy Arugula is used in soups, but cooked it looses almost all its flavor. The term "Rocket" is also loosely used for a number of other peppery herbs.
