Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- The main ingredient; browning in hot fat adds savoury flavour to its surface.
- Flour
- Coats the liver for browning and thickens the sauce at the end.
- Bacon
- Adds fat and savoury, smoky flavour to the stew.
- Onion
- Browned first, it adds sweetness and savoury depth to the sauce.
- Dried sage
- Adds an earthy, aromatic herb flavour that suits liver.
The step that matters
Simmer gently. Liver turns tough and grainy when boiled hard or cooked too long, so keep the stewpan at a gentle simmer for the stated time.
Swap the onion
How well each one fits the dish's main ingredients (liver, flour, sage, pepper):
- Shallotfits better
- Carrotfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against liver, flour, sage, pepper. Candidates are from the same food group and used in at least 100 recipes.
