Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Smoked salmon
- Main ingredient, providing the smoky flavor and the tender flaked texture of the dish.
- Beef or veal broth
- Provides the liquid and savory meaty base of the gravy.
- Catsup
- Adds sweetness and tang to the gravy, rounding out its flavor.
- Vinegar
- Adds acidity that sharpens the gravy and balances the richness.
- Butter
- Adds fat and richness, coating the salmon and keeping it moist.
The step that matters
Let it simmer for 10 minutes. Salmon proteins firm up and dry out under prolonged or vigorous heat. Keeping the gravy at a gentle simmer for a short time heats the fish through while keeping it tender and moist.
