Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Provides the main protein and rich flavour that the sauce is built around.
- Butter
- Carries heat into the liver and adds richness and a rounded flavour.
- Flour
- Thickens the stock into a smooth sauce as it cooks with the fat.
- Onions
- Add sweetness and body to the sauce as they soften and brown slightly.
- Curry powder
- Supplies the warm spice aroma that defines the dish.
The step that matters
Cooking the liver slowly. Liver turns grainy and tough when cooked too hot or too long, because its proteins tighten quickly. Gentle heat keeps it tender and moist while it cooks through.
