If you're an American thinking of Australia you probably think Kangaroos, G'day, Steve Irwin (RIP King), and Vegemite (and also terrifying spiders and snakes but we're not trying to dwell on that right now).
Listen, I've had vegemite before. It's just not good. I've decided this is a fact and not an opinion. It's like if you left roast beef in salt for a year and it all congealed into the least appetizing spread. I'm convinced the wonderful Australian people (shout out to my Australian camp counselors at Camp St. Charles. They were the best.) have trauma-bonded with Vegemite or something. You can't convince me anyone has ever tasted it and liked it on the first try.
Anyway, I hope the pizza goes well.
