Why it works: Parsley and butter are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Liver and Parsley
Ingredients
Directions
Prepare the liver
Wash the liver and boil it in minimal water for 5 minutes.
Chop or pound the liver with a small amount of the boiling liquid.
Prepare the parsley
Wash one-third of the bulk of parsley and boil it in a little salted water.
Drain and mince the parsley very finely.
Combine and warm
Mix the minced parsley with the liver and add it to the melted butter.
Warm the mixture gently, but do not let it boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Forms the main body of the dish, giving it a rich, savoury texture when chopped or pounded.
- Melted butter
- Adds fat and smoothness, carrying flavour and helping the mixture stay soft and spreadable.
- Parsley
- Contributes fresh, green aroma and a light herbal flavour that balances the rich liver.
The step that matters
Warm the mixture gently, but do not let it boil.. Butter and liver proteins are sensitive to high heat. Boiling can cause the butter to separate and the liver to turn grainy and tough, so gentle warming keeps the mixture smooth and cohesive.
