The cucumber (Cucumis sativus)is a widely cultivated plant in the gourd family Cucurbitaceae, which includes squash, and in the same genus as the muskmelon.
A gherkin is not only a pickle of a certain size but also a particular species of cucumber: the West Indian or Burr cucumber (Cucumis anguria), which produces a somewhat smaller fruit than the garden cucumber (Cucumis sativus). Standard pickles are made from the West Indian cucumber, but the term gherkin has become loosely used as any small cucumber pickled in a sweet vinegar brine, regardless of the variety of cucumber used.
A "kosher" dill pickle is usually not kosher in the sense that it has been prepared under rabbinical supervision, which would ensure that no non-kosher ingredients were used, and that no utensil in contact with the pickles had ever been in contact with food that was not kosher. Rather, it is a pickle made in the traditional manner of Jewish New York City pickle makers, with generous addition of garlic to the brine.
