Why it works: Mushroom and beef are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
An Excellent Hash of Cold Beef
Ingredients
Directions
Make the sauce
Melt the butter in a thick saucepan over medium heat.
Add the minced herbs and chopped onion or eschalots; cook until lightly browned.
Stir in the flour, cayenne, mace or nutmeg, and salt; cook until well colored.
Pour in the broth or gravy and let it boil gently for 15 minutes.
Strain the mixture, then add the mushroom or catsup.
Add the beef and serve
Add the cold beef and keep it by the fire until heated through, but do not let it boil.
Serve in a hot dish, garnished with fried or toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries the onion and herbs and browns them, adding richness to the sauce.
- Flour
- Thickens the broth into a sauce that clings to the beef.
- Broth or gravy
- Forms the liquid base of the hash, carrying the flavour through the dish.
- Onion or eschalots
- Browning softens and sweetens them, building savoury depth in the sauce.
- Mushroom or compound catsup
- Adds a concentrated savoury, umami flavour to the finished sauce.
- Cold beef
- Is the main protein, gently warmed through in the sauce.
The step that matters
Heating the beef without boiling. Boiling toughens cooked meat and makes it dry and stringy, so the beef should only be warmed through gently in the hot sauce.
Swap the mace
How well each one fits the dish's main ingredients (butter, onion, flour, pepper, mushroom, beef, bread):
- Garlicfits better
- Thymefits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against butter, onion, flour, pepper, mushroom, beef, bread. Candidates are from the same food group and used in at least 100 recipes.
