What's an ingredient they bought — possibly in a fleeting moment of adventuresomeness —and never used?

To me it is a ridiculous euphemism, the way you might refer to cannibals as “practitioners of nontraditional culinary adventuresomeness.”

The movie is a testament to the resilience and adventuresomeness of older people.

It’s full of stories and attitude, more flowery and, oh, snobby, than the gritty adventuresomeness of Banana Republic.

But toughness was not their quality—adventuresomeness was—and a mean determination to explore everything that interested them, from one-eyed chickens high- stepping in their penned yards to Mr. Buckland Reed’s gold teeth, from the sound of sheets flapping in the wind to the labels on Tar Baby’s wine bottles.
