A "kosher" dill pickle is not necessarily kosher in the sense that it has been prepared in accordance with
Jewish
dietary law. Instead, it is a pickle made in the traditional manner of Jewish New York City pickle makers,
with
a
generous addition of garlic and dill to natural salt brine.[20][21][22]
In New York terminology, a "full-sour" kosher dill is fully fermented, while a "half-sour", given a shorter
stay
in the
brine, is still crisp and bright green.[23]
Dill pickles, whether or not described as "kosher", have been served in New York City since at least
1899.[24]
