Adventurous? Just not a part of my upbringing, and let me say, knowing now the different kinds available, mom had her hands full coming up with ideas every night. We didn't eat out very often and only brought home pizza once in a blue moon, usually in summer when the kitchen was too hot (no A/C back then).
As an adult and having been married to two very different, but finicky eaters, I couldn't haven't gotten away with it either.
They each wanted to see what they were eating so they could pick it apart.
Being on my own since about '89, I have increased my repitoire 10 fold, but still haven't found the need, or desire.
No offense given or taken.
