A kosher dill pickle, also called a dill pickle, kosher pickle, or kosher dill, is a cucumber pickle made in the traditional manner of Jewish New Yor City pickle makers, with a salt brine and large amounts of garlic and dill.
In New York terminology, a "full-sour" kosher dill is one that has fully fermented, while a "half-sour", given a shorter stay in the brine, is still crisp and bright green. Elsewhere, these pickles may sometimes be termed "old" and "new" dills.
