Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,118 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. 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 ham mixture
Pound the chopped ham with butter, salt, pepper, cayenne, and carmine until smooth.
Sieve the mixture to achieve a fine texture.
Assemble and garnish
Fry the bread slices until golden brown.
Spread the ham mixture on the fried bread, piling it higher in the center.
Decorate with seasoned whipped cream.
Garnish with chopped truffle, sieved egg yolk, and parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked ham
- Provides the main savoury flavour and the body of the spread.
- Butter
- Adds fat that makes the ham mixture smooth and rich in texture.
- Hard-boiled egg yolk
- Adds richness and a soft, creamy texture to the spread.
- Bread
- Forms the crisp, golden base that holds the ham mixture.
- Whipped cream
- Adds lightness and a cool, creamy topping over the rich spread.
The step that matters
Sieve the mixture to achieve a fine texture.. Pounding alone leaves fibres and lumps in the ham. Pressing it through a sieve breaks them down, giving the smooth, even spread the dish depends on.
Flavor stand-ins for the parsley
How well each one fits the dish's main ingredients (ham, pepper, butter, egg, bread, cream, truffle):

- Parsleythe original
- Celeryabout as good a flavor fit
Fit is the average pairing score against ham, pepper, butter, egg, bread, cream, truffle. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
