Why it works: Bread and butter 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 ↓
Vermicelli Eggs
Ingredients
Directions
Prepare the eggs and toast
Boil the eggs for 20 minutes, then cool them.
Separate the yolks from the whites and finely mince the whites.
Toast the bread slices in the oven until lightly browned.
Make the sauce
In a saucepan, melt the butter, then stir in the flour to make a roux.
Gradually add the milk, stirring until the sauce thickens.
Stir in the minced egg whites, then pour the hot sauce over the toasted bread.
Finish
Pass the yolks through a fine sieve and sprinkle over the dish.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they 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
- Yolks add richness and colour; minced whites set when heated and add body to the sauce.
- Butter
- Fat that melts with the flour to form the roux, carrying flavour into the sauce.
- Flour
- Starch that, cooked in the butter, thickens the milk into a smooth sauce.
- Milk
- Liquid that becomes the sauce, thickening as its starch and proteins are heated.
- Bread
- Toasted base that gives a crisp, absorbent surface to hold the hot sauce.
The step that matters
Adding the milk gradually to the roux. Flour starch must be cooked in the butter and dispersed evenly in the liquid. Adding milk slowly while stirring prevents lumps and lets the sauce thicken smoothly.
