Pickle, Gherkin or just Pickled Cucumber- depending upon where you are in the world; are sandwich staples and side accompaniments mostly. Unless you obviously want to gobble that entire thing down on its own. But as far as I can remember, my first interaction with gherkins was in first year of college, in Delhi, when Subway became a popular eating choice. Many a times I would pick up bottles of gherkins at the supermarket and put it back, thinking do I really need that? For however much the temptation, one masters the art of resistance while living on a student/new earner budget.
