It's Vegemite, a classic Australian spread made from spent brewer's yeast, and these kids are tasting it for the first time on video.
"Cookies!" screams one tiny tot, who could not be more wrong, after he's presented with a tray of crackers smeared in Vegemite.
"It looks amazing," another kid proclaims, but "it tastes terrible."
Perhaps unsurprisingly, the video hasn't been well received by Australian media, with NineMSN admonishing the "little ingrates" for speaking ill of the salty spread they deem Australia's "national treasure."
