“Many items there are staples. Others are ingredients that, like salt, are only good in combination with something else. Some things you keep around are healthy, if not very tasty, while a few might count as junk food. (A couple of scholarly presses are indeed known for their Pop-Tarts.) And it’s hardly a decent pantry if you don’t have a few impulse purchases you later regret, or gourmandizing experiments that didn’t quite pan out.”
