Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts with the flour to form a roux that thickens the sauce and adds richness.
- Flour
- Thickens the sauce as it cooks with the butter, giving it body.
- Gravy
- Forms the liquid base of the sauce, adding savory meaty flavor.
- Mushroom catsup
- Adds deep savory umami flavor to the sauce.
- Lemon juice
- Adds acidity that brightens the rich sauce.
- Essence of anchovies
- Adds a salty, savory depth that rounds out the flavor.
The step that matters
Simmer the mixture for a few minutes. Simmering cooks the raw flour taste out of the butter and flour mixture and lets the sauce thicken evenly. Boiling hard can scorch the bottom of the pan or break the sauce, so keep it at a gentle simmer while stirring.
