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

What each ingredient does

Eggs
Set and enrich the sauce, giving it body and a rich, creamy texture as they cook gently.
Flour
Thickens the gravy into a smooth sauce when cooked with the butter.
Butter
Adds richness and smoothness, and helps the flour thicken the sauce evenly.
Veal gravy
Forms the liquid base of the sauce, providing its main savory flavor.

The step that matters

Adding the eggs off the heat. Eggs thicken by gentle heat and can scramble if they meet a boiling liquid. Removing the pan from the heat before stirring them in lets them combine smoothly and set into a silky sauce.
