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

What each ingredient does

Butter
Adds fat and richness, carrying flavour through the gravy.
Onion
Softens and sweetens as it cooks, building a savoury base.
Brown haricot stock
Forms the liquid base that the flour thickens.
Flour
Starch that thickens the liquid into a smooth, body-rich gravy.
Browning sauce
Darkens the colour of the gravy.

The step that matters

Stirring in the flour. Flour thickens only when its starch is evenly dispersed in the hot liquid. Added in clumps or unstirred, it forms lumps with dry, uncooked centres, so it should be stirred in gradually and evenly.

Swap the onion

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

  1. Shallotfits better
  2. Chivefits better
  3. Arrowrootfits better
  4. Onionthe original

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