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 ↓

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Flour
- Thickens the hot milk into a smooth, spoonable sauce.
- Spanish onions
- Add sweetness and savory depth as they brown in the fat.
- Hard boiled eggs
- Provide body and richness, held within the sauce.
- Fat
- Carries the onion flavor and helps it brown.
- Hot milk
- Forms the creamy liquid base that the flour thickens.
The step that matters
Blend in flour, then add hot milk gradually. Adding the milk slowly while stirring keeps the flour evenly dispersed, so the sauce becomes smooth instead of lumpy.
Swap the onion
How well each one fits the dish's main ingredients (flour, milk, parsley, pepper, egg):
- Shallotfits better
- Carrotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against flour, milk, parsley, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
