It's a question that has plagued no one, but at some point in their lives tens of millions of people have wondered to themselves "why does my sandwich always come with a pickle?"
These people have the right to know why there's always a pickle with their sandwich, and why deli pickles are so delicious you kinda want another one after you finish the first.
The pickle and sandwich connection can be drawn directly back to the Jewish delis in New York around the turn of the 20th century, when standard sandwich practices were being introduced.
These delis included a homemade pickle with the sandwich as a palate cleanser, but pickles soon became such a popular snack food that the Pickle Wars went down in the Lower East Side.
And since NY's Jewish delis had so much influence on all the other sandwich shops, delis, grinder and sub shops to come the pickle-sandwich pairing continued until it became the norm.
