In other words, what foods did you not grow up with, which you’ve had to get used to eating now as an adult? I grew up in a northern household and we weren’t well-off so it was mainly pies and stew!
I’ll start:
Pesto
Smoked salmon
Curry
Risotto
Steak
Sour cream/creme fraiche/mascapone
Asparagus
Olive oil
