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

What each ingredient does

French dinner roll
Provides a crisp, toasted base that holds the topping without going soggy.
Butter
Adds richness and a savoury browned flavour to the toasted inside of the bread.
Astrachan caviar
Supplies the salty, briny flavour that is the main feature of the toast.
Shallot
Adds a mild, sharp onion-like sweetness that complements the caviar.
Lemon juice
Adds acidity that brightens the rich, salty caviar.

The step that matters

Toasting the slices until golden brown. Toast needs enough browning to be crisp and sturdy, so it does not turn soggy under the topping. Underdone bread stays soft and damp, while over-browned bread turns bitter.

Swap the shallot
