Pies in general are weird across the world. Where I was growing up, sweets in general weren't in great supply, but a pie was a great way of using up excess fruit after canning/preserving and that's when we got it. In Britain they have meat-based (like pot pies in the US, but more stodgy).
Pumpkin pie and cheesecake and great cuts of steak I didn't get until I got to the US. I think many people make it too sweet, but you can cut the sugar for more flavor. My wife makes amazing Amaretto or Champagne cheesecake.
The first time I came to the US, we went to a steakhouse and they had a 16oz ribeye for $25, I wasn't sure how much 16oz was, or what ribeye meant but any steak for under $30 sounded good, the biggest steak I had seen in my life. It's weird going from a culture where meat was a special side dish to where meat is the main dish and excess is basically affordable for any class of society, like Thanksgiving turkey, steak, burgers.
Vegemite/marmite is classically what's leftover after brewing beer, but it works adding it to some things in small amounts. Basically an umami taste much like seaweed or soy sauce in Asian dishes.
