Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish drippings
- Carry the savory fat and flavor that form the base of the gravy.
- Browned flour
- Thickens the liquid so the gravy coats the fish and clings to it.
- Water or stock from fish trimmings
- Provides the liquid that turns the roux-thickened base into a sauce.
- Bovril
- Adds deep savory flavor and a darker color to the gravy.
- Worcestershire sauce or ketchup
- Adds tangy, savory depth that balances the richness of the drippings.
- Vinegar from bottled capers
- Adds acidity that brightens the gravy and sharpens the flavor.
The step that matters
Bring the mixture to a boil. Flour only thickens fully when the liquid reaches a boil, so the gravy can stay thin or taste raw if it is not heated enough.
