Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Breaks down during simmering to thicken and enrich the sauce with a deep, savoury flavour.
- Suet
- Adds richness and fat, giving the sauce a rounder mouthfeel.
- Red wine
- Adds acidity and depth, helping to balance the rich liver flavour.
- Onions
- Break down into sweetness and body, building the base flavour of the sauce.
The step that matters
Simmering until fully cooked. Liver must cook through to be safe and to lose its raw texture, but overheating or boiling too hard can make it grainy and tough. A gentle simmer cooks it evenly while keeping the sauce smooth once strained.
Swap the onion
How well each one fits the dish's main ingredients (liver, red wine):
- Tomatofits better
- Shallotfits about as well
- Onionthe original
- Carrotfits less well
Fit is the average pairing score against liver, red wine. Candidates are from the same food group and used in at least 100 recipes.
