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
- Cooked chopped meat
- Forms the bulk of the hash and provides savory flavor as it browns.
- Onion
- Adds sweetness and aroma as it softens and caramelizes in the pan.
- Butter
- Adds fat and richness and helps the surface brown.
The step that matters
Cooking the mixture into a flat cake until well browned. Browning depends on direct contact with the hot pan and enough dry surface. Pressing the hash flat and leaving it undisturbed long enough builds a crust through the Maillard reaction, which gives flavor. Stirring too often or adding too much water steams the mixture instead.
Swap the onion
How well each one fits the dish's main ingredients (meat, butter, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against meat, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
