Morning, all!
Etymological note of the day: the "h" in gherkin is a 19th century addition to the Dutch/German gurken, apparently thrown in to preserve the hard "g" sound (see also "ghost"). Why that's only found in a small handful of common English words ("ghetto" being the only other common word I can think of, and the h in that came through the Italian anyhow), I have no clew.
As for my favorite pickles, I'm with Singdaw's DH as far as mass-produced stuff goes. Back in the day, though, I used to pick up spicy pickles from Gus's on the Lower East Side, along with a large tub of jalapeno-stuffed olives. How my stomach lining doesn't look like Swiss cheese is anybody's guess.
