This was my favorite since childhood (from a German Deli no less):
It used to be carried at the pig in Cedarburg (no more), Grash's is a hit or miss, not at Larry's,
Sendiks only carries the walnut, and the overpriced Chairman Boob's place (The Marketplace) only carries the walnut as well.
Thanks in Advance!
(And to make everyone laugh - I used to love it as a kid with the Nabisco Bacon flavored crackers - something that is no more).
