Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Goose livers
- Provide the rich, soft, savoury base that gives the spread its main texture and flavour.
- Hard boiled eggs
- Add body and a firm, crumbly texture that helps bind the mashed liver mixture.
- Butter
- Adds fat and richness while cooking the livers, helping them turn soft and smooth.
- Grated onion
- Adds a sharp, aromatic note that balances the richness of the liver.
The step that matters
Cook the goose livers until soft. Undercooked livers stay firm and grainy, so they will not mash into a smooth spread; cooking them gently until just soft gives a creamy texture without drying them out.
