Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Egg Vermicelli
Ingredients
Directions
Prepare
Boil the eggs for 20 minutes.
Separate the yolks and chop the whites finely.
Toast the bread; cut half into small squares and half into points or triangles.
Make and serve
In a saucepan, combine cream or milk, butter, flour, salt, and pepper to make a thin white sauce.
Stir the chopped egg whites into the hot sauce and pour it over the squares of toast.
Rub the yolks through a fine strainer over the dish and garnish with toast points and parsley.

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
- Whites set into the sauce for texture, and the rubbed yolks give a fine, crumbly topping.
- Bread
- Toasted pieces form the base and garnish, giving a crisp structure that holds the sauce.
- Cream or milk
- Forms the liquid base of the white sauce, adding moisture and a smooth, rich texture.
- Flour
- Thickens the cream or milk into a white sauce as its starch swells when heated.
- Butter
- Adds fat and richness to the sauce, giving it a smooth mouthfeel and flavor.
The step that matters
Make a thin white sauce. Flour must be cooked into the fat and liquid while stirring so starch swells evenly. Adding it unevenly or without stirring can leave lumps and an uneven, pasty texture.
Swap the parsley
How well each one fits the dish's main ingredients (egg, bread, cream, butter, flour, pepper):
- Nutmegfits better
- Parsleythe original
- Capersfits about as well
- Tarragonfits about as well
Fit is the average pairing score against egg, bread, cream, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
