Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lax (smoked salmon): Provides the main flavour and, pounded with butter, forms a spreadable topping.
Butter: Adds fat and richness, helping bind the pounded salmon into a smooth spread.
Cucumber: Adds a cool, crisp layer that contrasts with the rich salmon spread.
Vinegar: Adds acidity that brightens the cucumber and balances the rich salmon.
