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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
