A "piskey whickle" is a shot of your favorite whiskey (Jameson is recommended) with a pickle-brine chaser.
The pickle brine completely negates the whiskey's burn, and you're left with a clean palette that's ready for another shot!
It may sound strange, but I swear, it's surprisingly good!
Also known as a Pickleback or a Shecky Carmichael
