Why it works: Egg and bread match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 22,584 recipes mention both. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
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.
Poach and prepare the eggs
Poach the eggs in white stock.
Drain and trim the poached eggs.
Dish the eggs on fried bread croutons.
Make the sauce
Chop the onion and shallots finely.
Fry the chopped onion and shallots with a little butter in a stewpan.
Add parsley, bay leaf, and thyme to the stewpan.
Strain off the butter.
Add rich brown sauce and return it to the stewpan.
Add sliced mushrooms and lemon juice.
Finish and serve
Place the dish with the eggs in the oven at 400°F (200°C) for a few minutes.
Sauce over the dish.
Garnish with fillets of anchovies and stoned olives.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and form the main body of the dish, providing richness when cooked gently in stock.
- Rich brown sauce
- Adds savoury depth and moisture that coats the eggs and croutons.
- Onion and shallots
- Build a sweet, aromatic base when softened slowly in butter.
- Mushrooms
- Add earthy flavour and a tender texture to the sauce.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances its fat.
The step that matters
Poach the eggs in white stock. Eggs cooked at too high a heat or for too long turn rubbery and break apart, so the stock should be kept at a gentle simmer and the eggs timed carefully.

Fit is the average pairing score against egg, bread, shallot, butter, parsley, thyme, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
