Whelks
Buccinum undatum
One of Scotland's most exported shellfish — almost the entire whelk catch goes to South Korea, where they're prized. Rarely seen on UK menus and almost never in supermarkets, which is a shame: properly cooked, they're firm, salty, and excellent value. Pot-caught, year-round, and low-impact.
Seasonality
Buying
Buy live or freshly cooked from a specialist fishmonger. Shells should be intact; cooked whelks should smell clean and saline.
Storage
Live: fridge in a damp cloth for up to 24 hours. Cooked: eat within 2 days.
Cooking methods
Traditional seaside whelk and vinegar. Garlic butter with parsley. Added to a shellfish paella or seafood pasta.

Langoustine
Scotland’s most valuable seafood export — and, bafflingly, a product most Scots have never eaten. Also called Dublin Bay prawns, Norway lobster, or scampi in its cheapest incarnation. Fresh, whole langoustines landed on the west coast are one of the great seafood experiences in the world.
North Sea Cod
The backbone of Scottish fish and chips. North Sea cod has been through stock collapse and recovery cycles; look for MSC-certified Icelandic or Barents Sea if you’re unsure about provenance.
Scottish Salmon
Scotland’s most exported food product by value. Virtually all salmon you buy is farmed — wild Atlantic salmon is critically endangered and mostly reserved for catch-and-release sport fishing. Look for RSPCA Assured or organic labels for higher welfare.
