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
Prepare the eggs
Poach the eggs in white stock, then drain and trim them.
Place the eggs on fried bread croutons.
Make the sauce
In a stew-pan, fry the onion and shallots in butter until soft.
Add parsley, bay leaf, and thyme, then strain off the butter.
Stir in the brown sauce, sliced mushrooms, and lemon juice.
Finish and serve
Place the dish with the eggs in the oven for a few seconds.
Sauce the eggs, garnish with anchovies and fried parsley, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Form the main body of the dish, set firm when poached and held on the croutons.
- Shallots
- Add a mild, sweet aromatic base when softened gently in butter.
- Onion
- Softens in butter to build a sweet, savoury base for the sauce.
- Butter
- Carries the aromatics and adds richness and a rounded flavour.
- Brown sauce
- Provides the body, depth and colour of the finished sauce.
- White stock
- Poaches the eggs, lending a light savoury flavour to them.
The step that matters
Poaching the eggs. Eggs poached in simmering stock hold their shape when the white sets quickly around the yolk. Too vigorous a boil scatters the white, so trimming and draining neatly afterwards matters.

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).
