PERHAPS you are one of the more than 5,000 subscribers to Popping Tins, an email newsletter devoted exclusively to tinned seafood. Perhaps you belong to a tinned-fish-of-the-month club, or have leafed through a tinned-fish-focused cookbook that tells you how best to cook a food already cooked.

Perhaps you, like some TikTok users, even hold a weekly “tinned-fish date night” with your spouse.
