Why it works: Egg and bread are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 22,662 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
Nested Eggs
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Carefully separate the egg whites from the yolks, keeping the yolks in their shells.
Place the yolk-filled shells in a cool place until ready to use.
Toast the bread slices and spread them with pounded chicken livers.
Assemble and bake
Beat the egg whites until very stiff and heap them on the toast.
Make a hollow in the center of the egg white heap and gently drop in the yolks.
Bake in a very hot oven at 400°F (200°C) for three minutes or until lightly browned.
Serve
Sprinkle chopped parsley over each serving and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites whip into a stiff foam that holds its shape, while the yolks set softly in the hollow.
- Bread
- Toasted slices give the dish a crisp base that supports the egg white heap.
- Chicken livers
- Pounded livers add a rich, savoury layer spread over the toast beneath the eggs.
The step that matters
Beat the egg whites until very stiff. Stiffly beaten whites trap air in a strong foam that holds its heap on the toast. Underbeaten whites collapse and spread, so the yolks sink into a flat layer instead of sitting in a well.
Swap the parsley
How well each one fits the dish's main ingredients (egg, bread, chicken, liver):
- Garlicfits about as well
- Capersfits about as well
- Parsleythe original
- Thymefits about as well
Fit is the average pairing score against egg, bread, chicken, liver. Candidates are from the same food group and used in at least 100 recipes.
