Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Milk and flour 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
- Eggs
- Form the main body of the dish, set firm by boiling.
- Milk
- Forms the liquid base of the cream sauce.
- Flour
- Thickens the hot milk into a smooth sauce as its starch swells.
- Onion
- Flavours the milk while it soaks, then is removed.
The step that matters
Thicken the milk with flour, stirring until smooth. Flour must be fully dispersed in the milk and the sauce heated so its starch swells evenly. Adding flour without stirring or keeping the sauce cool leaves lumps and a thin, uneven texture.
Swap the onion
How well each one fits the dish's main ingredients (egg, milk, pepper, flour):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against egg, milk, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
