Why it works: Liver and butter are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 2,065 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

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 a meaty, rich texture.
- Butter
- Adds fat for frying and helps the liver brown and develop flavour.
- Tomatoes
- Supply moisture and acidity that form the sauce the liver cooks in.
The step that matters
Fry the liver for 1 minute on each side until glazed. Liver is lean and its proteins tighten quickly under heat. A short, hot sear keeps it tender, while longer frying makes it dry, grainy and tough. The later simmer in tomatoes adds more cooking time, so the first sear should be brief.
