Brie is one of those cheeses that only shows up at fancy parties. You don't see brie next to the sweaty cubes of yellow and orange cheese served at senior centers. That's when the cheese doesn't even really have a name. It's just labeled by its color. Does that make it blue cheese when it molds? Brie is one of the most fantastic cheeses, so you could practically put it on anything and you're going to be good.
Brie and jam doesn't seem that odd to me actually. I usually have brie with other appetizers like bread and jam, and we usually just mash all those things together into a ball anyway. Why not make a classy little sandwich? This is the type of sandwich that the weird kid in middle school would eat. Everyone would be thinking, "don't you realize you're 10?"
