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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Provides the main body, meaty flavor and bulk of each meatball.
- Cracked meal
- Absorbs the milk and egg liquid and helps the patties hold together.
- Egg
- Binds the mixture, and its proteins set when heated to hold the shape.
- Sweet milk
- Adds moisture that keeps the patties tender rather than dry.
- Onion
- Adds aroma and moisture to the mixture as it cooks.
The step that matters
Forming the patties. The mixture must be firm enough to hold its shape. The cracked meal soaks up the milk and egg, and the egg sets with heat, so the patties keep their form while boiling in the sauce.
Swap the onion
How well each one fits the dish's main ingredients (meat, milk, egg, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against meat, milk, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
