Sardines were a plentiful, inexpensive especially nutritious protein source during the Depression and World War II and sardines and crackers were a pantry staple the whole family enjoyed when I was growing up. Haven't had them in years but now that I'm thinking about it, I might buy a tin if they aren't too expensive now.
Bagels and cream cheese or other schmears have been part of American culture since at least the 1960s. Originating I think with Polish Jewish immigrants they gradually became American mainstream. There are now shops selling pretty much exclusively bagels and they seem to be thriving.
I only recently had opportunity to experience tiramisu and loved it. I am very adventurous when it comes to food, am very eclectic in cuisine I enjoy, and I'll at least taste pretty much anything once. But some things that are supposed to be delicacies I haven't been able to develop a taste for: caviar, oysters on the half shell, sushi, scallops and some others.
