Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 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
- Underdone beef
- Forms the main body of the mincemeat and gives it its meaty texture.
- Fat
- Adds richness and moisture so the meat stays tender and flavourful.
- Vinegar
- Adds a sharp acidity that brightens the rich meat and fat.
The step that matters
Do not let it boil after adding the gravy and minced beef. Boiling again toughens the meat proteins and can make the fat separate out, leaving the mixture dry and greasy rather than tender and cohesive.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, vinegar, bread):
- Capsicumfits better
- Tomatofits better
- Onionthe original
- Mustardfits about as well
Fit is the average pairing score against beef, pepper, vinegar, bread. Candidates are from the same food group and used in at least 100 recipes.
