Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cold beef (in the method)
Provides the main meat; it is only warmed through, so it stays tender.
Flour
Thickens the broth into a smooth, lightly coating sauce as it cooks.
Onion or shallots
Adds sweetness and savory depth when browned in the butter.
Broth or gravy
Forms the liquid base of the hash, carrying the flavor of the dish.
Mushroom or compound ketchup
Adds concentrated savory, umami depth to the sauce.
Butter
Carries the aromatics and adds richness and browning to the base.

The step that matters

Add the cold beef off the boil. Once the beef is added, the sauce must stay below a boil. Boiling toughens meat proteins and can make the beef dry and stringy, so gentle heat warms it through while keeping it tender.

Swap the mace

How well each one fits the dish's main ingredients (butter, onion, flour, pepper, mushroom, bread):

  1. Thymefits better
  2. Garlicfits better
  3. Parsleyfits better
  4. Macethe original

Fit is the average pairing score against butter, onion, flour, pepper, mushroom, bread. Candidates are from the same food group and used in at least 100 recipes.
