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 ↓
Belgrad Eggs
Ingredients
Directions
Prepare
Remove the shells from the hard‑boiled eggs, chop the whites finely, and sieve the yolks separately.
Boil the milk in a saucepan.
Make the sauce
In a small bowl, mix the cornstarch with the olive oil, then add it to the boiling milk.
Stir in the chopped egg whites, salt, and cayenne pepper.
Assemble and serve
On a platter, layer the toasted bread with the milk mixture, followed by a layer of yolks, then the remaining whites, and finally the rest of the yolks.
Serve on lettuce leaves, garnished with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the main body of the dish, with whites chopped and yolks sieved for layering.
- Milk
- Forms the liquid base of the creamy sauce that moistens the bread and eggs.
- Cornstarch
- Thickens the boiling milk into a smooth sauce as its starch swells with heat.
- Toasted salt-rising bread
- Acts as the base layer that soaks up the milk mixture and holds the egg layers.
The step that matters
Adding the cornstarch mixture to the boiling milk. Cornstarch must be stirred into the hot milk and kept moving so it thickens smoothly; if it is added to cold liquid or left unstirred, it can clump or stay thin.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, milk, olive, pepper, bread, parsley):
- Capsicumfits better
- Tomatofits better
- Potatofits better
- Lettucethe original
Fit is the average pairing score against egg, milk, olive, pepper, bread, parsley. Candidates are from the same food group and used in at least 100 recipes.
