Cod we trust: 'Big five' fish now our favoured dish

A century ago, baked halibut in custard was framed as a child-friendly supper, but today’s home cooking has narrowed toward a so-called “big five” of seafood dishes. Research analyzing 100 years of Good Housekeeping recipes found that cooks have largely moved away from a wider range of fish options and instead rely on a small set that includes tuna and prawns. The study describes how fish recipes in the 1920s were used to teach housewives how to prepare seafood at home, while modern recipe patterns show a more consistent, repeatable go-to menu.
