Why it works: Butter and truffle are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,209 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Eggs with Chickens' Livers
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Season the livers with pepper and coarse sea salt.
Arrange the livers in a fireproof baking dish, adding a little butter between each.
Bake and serve
Bake in a 400°F (200°C) oven for a few minutes.
Remove from the oven and crack an egg between each liver.
Sprinkle with chopped truffles and add a little butter on top.
Return to the oven until the eggs are cooked, then serve immediately.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chickens' livers
- Provide the rich, savoury base that the eggs are baked on.
- New-laid eggs
- Set as they cook, forming a soft, creamy topping over the livers.
- Butter
- Adds richness and moisture, helping the livers and eggs cook gently.
- Chopped truffles
- Add a deep, earthy aroma to the finished dish.
The step that matters
Returning the eggs to the oven. Eggs set quickly once heat reaches the white and yolk, so leaving them in too long makes the yolks firm and chalky. Checking early keeps the yolks soft while the whites are just set.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
