In the USA, the term pickles refers specifically to
pickled cucumbers. These are known as gherkins (or, less formally, "wallies")
in the United Kingdom. (In the US, gherkins are small
pickles.) They may be produced by fermentation or by
simply treating cucumbers with vinegar. Pickles are often flavored with turmeric and dill. They
are generally used to add piquancy to a main meal, and on
or with hamburgers and other types of sandwiches.
Outside of the USA, the term "pickle"
sometimes refers to any sort of pickled food. These can
range from pickled onions
to complex pickles produced for the Indian market.
If a recipe calls for "pickles", it's the US
usage; if it is any other kind of pickle, it should be
more specific (i.e., pickled radish, pickled pepper, etc.).
