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 Sauce
Ingredients
Directions
Make the liver base
Wash the liver and boil it in 5 teaspoons of water for 10 minutes.
Chop the liver finely and pound it in a small amount of the boiling liquid.
Rub the mixture through a fine sieve.
Finish the sauce
Wash the parsley leaves and boil them in salted water until tender.
Drain the parsley and chop it finely.
Mix the chopped parsley with the liver and add ¼ cup of melted butter.
Warm the mixture gently without boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl or rabbit liver
- Forms the smooth, rich body of the sauce once cooked and sieved.
- Parsley leaves
- Adds fresh, green flavor and color to the sauce.
- Melted butter
- Adds fat, giving the sauce a smooth, glossy texture and rich mouthfeel.
The step that matters
Warm the mixture gently without boiling. High heat can cause the butter to separate and the proteins in the liver to tighten, leaving the sauce grainy or oily instead of smooth.
