Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sardines
- Form the main body of the dish and carry its flavour when fried until cooked.
- Heavy tomato sauce
- Provides acidity and body, coating the fish and adding moisture.
- Butter
- Adds richness and a smooth mouthfeel to the boiled tomato sauce.
The step that matters
Boiling the sauce with butter. Butter is added to the boiled sauce, so the sauce must be hot enough to melt and emulsify the fat evenly. Adding butter to cold or unboiled sauce can leave greasy pools instead of a smooth, glossy coating.
