Why it works: Liver and pepper are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 2,375 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Calf’s Liver
Ingredients
Directions
Cook the liver
Place the liver in a saucepan and cover it with cold water.
Boil for 45 minutes.
Remove the liver from the water and let it cool completely.
Prepare the mixture
Grate the cooled liver using a carrot grater.
Chop the bacon finely and mix it with the grated liver in a bowl.
Add the mixed herbs, salt, and pepper to the bowl and mix well.
Beat the egg yolks and cream together and add the beaten mixture to the liver mixture.
Heat and serve
Transfer the mixture to a saucepan.
Heat over low heat, stirring until very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Forms the main body of the dish, giving it a soft, rich texture when cooked.
- Bacon
- Adds fat and savory flavor that carries through the liver mixture.
- Egg yolks
- Bind the mixture and help it set into a cohesive, smooth texture when heated.
- Cream
- Adds moisture and richness, softening the texture of the liver mixture.
The step that matters
Heat over low heat, stirring until very hot. Egg yolks in the mixture can curdle or turn grainy if heated too fast or left unstirred. Gentle, constant stirring over low heat lets the yolks thicken the mixture evenly.
