What each ingredient does

Sardines: Provide the main savoury flesh that forms the spread's body and rich flavour.
Butter: Adds fat that makes the pounded mixture smooth and spreadable and carries flavour.
Worcestershire sauce: Adds savoury, tangy depth that complements the richness of the sardines.
Cayenne pepper: Adds heat and a sharp, peppery note that balances the fish's richness.
