Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Beef or Veal Hash
Ingredients
Directions
Prepare the hash
Chop cold beef or veal very fine, removing gristle and skin.
Mix with half as much chopped cold boiled potatoes; season with salt and pepper.
Sprinkle 1 tablespoon of flour over the mixture.
Make the sauce
In a stewpan, sauté chopped onion in butter until soft.
Add stock or water and boil down to half the quantity.
Combine and serve
Just before serving, add the beef and potato mixture and chopped parsley.
Let it scald for five minutes and serve on toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef or veal
- Provides the main meat flavour and body of the hash.
- Potatoes
- Bulk out the meat and add soft texture and moisture to the mixture.
- Flour
- Thickens the cooking liquid so the hash binds together.
- Onion
- Adds sweetness and aroma as it softens in butter.
- Stock or water
- Provides the liquid that is reduced to a flavourful, thickened moisture.
The step that matters
Boiling down the stock. Reducing the stock concentrates its flavour and thickens it slightly, so the hash is moist but not watery. Boiling too little leaves the mixture thin, while over-reducing can make it too dry or salty.
Swap the onion
How well each one fits the dish's main ingredients (beef, potato, pepper, flour, butter, parsley, bread):
- Chivefits better
- Carrotfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against beef, potato, pepper, flour, butter, parsley, bread. Candidates are from the same food group and used in at least 100 recipes.
