So, it happens that a number of Gristies are having soup-based lunches today. Me, I’m having chili. Which prompted a comment from a colleague: “Well, that’s a kind of soup, right?” Me: “Or is it a kind of stew?” Other colleague: “Or is stew a kind of soup?”

So, a few seconds googling some intense research has confirmed that this is a contentious question — even prompting a recent lawsuit — but it has not revealed a definitive answer.

Grist’s audience seems rather food savvy. So we turn to you to bring clarity to this intolerable murk. Enlighten us.
