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

What each ingredient does

Cheese: Provides flavor and, when melted or mashed with the other ingredients, a rich, binding texture.
Bread: Adds bulk to the paste and forms the base that holds the toast together.
Butter: Adds fat and richness, helping the paste mash smoothly and brown when toasted.
Egg yolks: Add richness and help bind the paste into a smooth, cohesive mixture.

The step that matters

Toast the snippets until brown. Browning comes from the Maillard reaction, which needs dry surfaces and enough heat. Stop too early and the snippets stay pale and soft; go too far and the fats and bread scorch and taste bitter.
