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 ↓

Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the egg
Separate the yolk and white of the egg.
Chop the white and keep the yolk warm.
Make the sauce
In a saucepan, melt the butter.
Stir in the flour, and cook for 1 minute.
Gradually add the cream or milk, stirring until thickened.
Season with salt and pepper.
Add the chopped egg white to the sauce.
Heat thoroughly.
Serve
Pour the mixture over the toast.
Press the yolk through a strainer on top.
Garnish with parsley.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Egg
- Egg white adds body and protein-based texture, while the strained yolk gives a rich, crumbly topping.
- Butter
- Adds fat and flavour to the base before the flour is cooked in.
- Flour
- Thickens the sauce when cooked briefly in butter, forming a roux.
- Cream or milk
- Forms the liquid base of the sauce, adding moisture and richness as it thickens.
The step that matters
Gradually add the cream or milk, stirring until thickened. Adding liquid slowly while stirring keeps the roux smooth; adding it all at once can leave lumps. Starch thickens as the sauce heats, so the sauce should be stirred until it coats a spoon.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, flour, pepper, cream):
- Nutmegfits better
- Parsleythe original
- Tarragonfits about as well
- Capersfits about as well
Fit is the average pairing score against egg, butter, flour, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
