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

What each ingredient does

Beef
Provides the main protein; thin slices cook through quickly in the simmering gravy.
Butter
Carries the flour and adds richness and flavour to the gravy base.
Flour
Thickens the gravy and, when lightly browned, adds a nutty, toasted flavour.
Stock or gravy
Forms the liquid base that gives the sauce its body and savoury flavour.
Worcestershire sauce
Adds savoury, tangy depth to the gravy.
Ketchup
Adds sweetness and acidity that rounds out the gravy's flavour.

The step that matters

Cook the flour until lightly browned. Flour must cook in the melted butter long enough to lose its raw taste and gain toasted flavour; stirring prevents lumps and scorching before the liquid is added.

Swap the potato

How well each one fits the dish's main ingredients (beef, butter, flour, sauce, ketchup, pepper):

  1. Capsicumfits better
  2. Shallotfits better
  3. Horseradishfits better
  4. Potatothe original

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