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

What each ingredient does

Caviare
Provides the main flavour and a briny, luxurious topping.
Butter
Adds fat and richness, and helps the caviare sit on the toast.
Thick slices of bread
Forms a crisp, sturdy base that holds the topping.

The step that matters

Toasting the bread until golden brown. Toasting dries the surface and creates browning flavour, so the bread stays crisp and does not turn soggy under the butter and caviare.

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.
