Why it works: Parsley and pepper 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 ↓
Croutons of Ham
Ingredients
Directions

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Sets when warmed, binding the mixture and giving it a thick, spreadable body.
- Butter
- Adds richness and a smooth mouthfeel that carries the flavor of the other ingredients.
- Chopped ham
- Provides the savory, salty meat flavor that forms the base of the topping.
The step that matters
Warm the mixture until the egg yolk just sets. Egg yolk proteins coagulate gently at moderate heat, thickening the mixture. If the heat is too high or the mixture is left too long, the proteins tighten too far, turning grainy or scrambled instead of smooth.
Swap the chive
How well each one fits the dish's main ingredients (ham, butter, parsley, egg, pepper):

Fit is the average pairing score against ham, butter, parsley, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
