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 ↓
Beef Collops, Minced
Ingredients
Directions
Prepare
Remove all skin from the rump steak and mince it finely.
Make the collops
In a saucepan, heat the butter or beef dripping over medium heat.
Add the chopped onion and flour, stirring until nicely browned.
Add the minced meat and turn it with a fork for about 10 minutes.
Season with pepper and salt, then add enough boiling water to cover the meat.
Close the lid and let it simmer gently for about 40 minutes.
Serve
Serve hot with mashed potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump steak
- Forms the main body of the dish; minced meat becomes tender as it simmers.
- Flour
- Browns with the onion and thickens the cooking liquid into a light gravy.
- Onion
- Adds savoury sweetness as it softens and browns in the fat.
- Butter or beef dripping
- Carries heat for browning the onion and flour and adds rich flavour.
The step that matters
Browning the onion and flour. Cooking the flour in fat until nicely browned develops a nutty flavour and colour before liquid is added. Stirring keeps it from scorching, which would taste bitter.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, pepper, meat):
- Shallotfits better
- Potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against butter, flour, pepper, meat. Candidates are from the same food group and used in at least 100 recipes.
