Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the fat and liquid into a smooth gravy as it cooks.
- Butter
- Adds richness and fat that carries flavor through the gravy.
- Fat from fried fish
- Gives the gravy its savory fish flavor and forms the base for the roux.
The step that matters
Stirring the flour into the hot fat. Flour must be stirred constantly into the hot fat so it cooks evenly and coats each grain with fat. Without thorough stirring, lumps form and the flour tastes raw when the gravy is later thinned with liquid.
