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 ↓

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Egg
- Binds the mixture so the meatballs hold their shape.
- Bread crumbs
- Absorb moisture and soften the texture of the meatballs.
- Flour
- Thickens the mixture slightly and helps the outside brown when rolled and fried.
- Onion
- Adds moisture and savory flavor to the meat.
The step that matters
Moistening the mixture. Add only a little water or cold gravy at a time. Too much liquid makes the mixture soft and hard to shape, while too little leaves the meatballs dry and crumbly.
Swap the onion
How well each one fits the dish's main ingredients (meat, egg, bread, flour, pepper):
- Shallotfits better
- Asparagusfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against meat, egg, bread, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
