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 ↓
To Hash Beef
Ingredients
Directions
Prepare the beef
Hang raw beef until tender, then cut into thin slices.
Place slices in a saucepan with enough water to cover them, sweet herbs, onion, pepper, and salt.
Cover and simmer until tender.
Make the gravy
Add port wine and shallot vinegar, then warm the mixture.
Strain the gravy through a fine sieve to remove herbs and vegetables.
Return the gravy to the saucepan with the beef and thicken with butter kneaded in flour and brown sugar.
Finish the hash
If using cooked meat, mince shallot and onion, then fry in butter.
Add flour, a little gravy, and walnut liquor or ketchup, and bring to a boil.
Add the thin slices of beef and heat through without boiling.
Optionally, add sliced potatoes and onions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw beef
- Provides the main meat; long hanging and simmering make it tender enough to slice thin.
- Flour
- Thickens the gravy by swelling with liquid, giving the sauce body.
- Butter
- Adds richness and flavor to the thickening and to the frying of the shallot and onion.
- Port wine
- Adds sweetness and depth of flavor to the gravy.
- Shalot vinegar
- Adds acidity that brightens the gravy and balances the richness.
- Brown sugar
- Adds sweetness and a hint of caramel flavor to the gravy.
The step that matters
Heat through without boiling. Once the thin beef slices go in, boiling toughens the meat and can make the gravy break or thicken unevenly, so keep it at a gentle heat.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, pepper, port wine, vinegar, butter, flour, sugar):
- Capsicumfits better
- Shallotfits better
- Mustardfits about as well
- Onionthe original
Fit is the average pairing score against beef, pepper, port wine, vinegar, butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
