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

What each ingredient does

Bread
Forms the crisp, hollow base that holds the filling.
Caviare
Provides the main salty, briny flavor and the luxurious topping.
Butter
Adds richness and a smooth, fatty mouthfeel to the bread.
Lemon
Adds acidity that brightens the rich caviare and butter.

The step that matters

Fry the bread until light brown. Frying until light brown dries and crisps the bread through browning, so it stays firm enough to hold the filling without going soggy.

Swap the lemon

How well each one fits the dish's main ingredients (bread, butter, pepper):

  1. Lemonthe original
  2. Figfits about as well
  3. Plumfits less well
  4. Mangofits less well

Fit is the average pairing score against bread, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
