While there's a lot of subjectivity when it comes to food, certain food truths we hold self-evident across communities large and small, whether they stem from cultural norms, regional trends, or otherwise. The vast majority of people I know, for example, agree that you don't put salt in your coffee. I am generally a live and let live sort of person, especially when it comes to choices made that have absolutely no bearing on my daily existence—like someone else's food preferences. But there are some such preferences—choices, hankerings, what have you—that leave me wrinkling my brow in puzzlement and, sometimes, hidden disgust. My girlfriend, for example, is all about pineapple and onion on her pizza. There aren't many pizza topping combinations I personally want to eat less. What about you all? What are some things you've seen other folks consume by choice that leave you utterly bewildered? On the flip side, do you find yourself craving certain food preparations/combinations/etc. that leave those around you puzzled by your choices? What, if anything, might we all have in common in terms of what we agree we just won't eat?
