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

What each ingredient does

Boston brown bread: Provides a sturdy, lightly sweet base that holds the toppings.
Hard boiled egg whites: Form a firm, mild ring that holds the filling in place.
Caviare: Adds salty, briny flavour and a distinctive texture as the main topping.
Soft butter: Binds the filling and adds richness and a smooth mouthfeel.
Cucumber: Adds cool, crisp texture and fresh moisture against the rich filling.
Lemon juice: Adds acidity that brightens the rich butter and caviare flavours.
