Alright, so that last one is less universal. But for the past few years it's been a fixture of the Pickle Guys' storefront on the Lower East Side, a neighborhood that was once one of the greatest hubs of America's Jewish community. Back in the day it was home to countless shops where you could fish a pound of kosher dills out of wooden barrels for a few pennies. Today, almost all of those pickle shops are gone, but The Pickle Guys carry the tradition on, and come Passover they turn their attention to one particular pickled piece of produce: horseradish. A lot of it. 2,700 pounds, owner Alan Kaufman estimates, for the season.
