Heinz's new Balsamic Vinegar Ketchup sounds like a winner, right? Upping the balscidity (new word) in lieu of the traditional distilled white vinegar gives it a mild kick without completely throwing off the familiar taste of ketchup.
This is actually a pretty big move for Heinz, a bastion of ketchup tradition; they haven't released a new flavor in about a decade. (Remember green ketchup in the early 2000s?) Yet the new flavor doesn't taste that dramatically different from "normal ketchup." You certainly pick up on more of an umami-based depth and richer balsamic tang, but it's still the same sweet, sticky Heinz underneath.
