Why it works: Egg and butter match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and 118,511 recipes mention both. Both carry nonanal, which smells fat, citrus. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the eggs
Boil the eggs for 15 minutes.
Make the sauce
Melt the butter over low heat in a frying pan, being careful not to burn it.
Add the flour to the melted butter and mix until smooth.
Gradually add the stock and cream, stirring continually until it boils.
Season with salt and pepper, then keep the sauce warm over a tea kettle.
Assemble and serve
Shell the eggs, cut the whites into thin shreds, and chop the yolks into tiny squares.
Pile the yolks in the center of a shallow heated dish and arrange the whites around them.
Stir the sauce and pour it around the eggs before serving.

Flour and butter share little aroma chemistry, yet 122,858 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Form the dish itself; the whites are shredded and the yolks chopped for presentation.
- Butter
- Provides fat and a rich flavor as the base for the roux.
- Flour
- Thickens the butter into a roux that gives the sauce body.
- Cream
- Adds richness and smoothness, softening the sauce's texture.
- White or veal stock
- Supplies savory depth and liquid that thickens with the roux into the sauce.
The step that matters
Melt the butter gently. Over low heat the butter melts without browning or burning, which would give the sauce a bitter, scorched taste. Adding the flour and stock only after the butter is smooth keeps the roux even, so the sauce thickens without lumps.
