Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Beauregard Eggs
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 the eggs
Boil the eggs for 20 minutes, then drop them in cold water.
Peel and chop the egg whites, and rub the yolks through a sieve.
Make the sauce
In a saucepan, melt the butter, add the flour, and cook until smooth.
Gradually stir in the hot milk, adding the bay leaf and onion piece, then remove them.
Assemble and bake
Arrange the buttered toast on a dish and cover with a layer of the sauce.
Add the chopped egg whites, seasoning with pepper, salt, and a dash of Worcestershire sauce.
Layer the yolks on top, adding more sauce and seasoning each layer with salt and pepper.
Set in the oven at 400°F (200°C) for 1 minute before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites set into structure while the rubbed yolks add richness and a smooth, creamy texture.
- Butter and flour
- Cooked together they form a roux that thickens the milk into a smooth, stable sauce.
- Hot milk
- Forms the liquid base of the sauce, adding moisture and creaminess once thickened.
- Bread
- Buttered toast gives a sturdy base that soaks up sauce and adds a golden, toasted flavor.
The step that matters
Thickening the sauce. Flour must be cooked in the melted butter until smooth before the hot milk is added gradually, or the sauce will turn lumpy instead of creamy.
Swap the onion
How well each one fits the dish's main ingredients (egg, flour, butter, milk, bread, pepper, sauce):
- Capsicumfits better
- Shallotfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against egg, flour, butter, milk, bread, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
