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

What each ingredient does

Flour
Thickens the sauce as its starch swells and sets when heated in the butter and liquid.
Butter
Carries flavour and fat, and browns with the flour to deepen the sauce's colour and taste.
Minced onion
Releases sweet, savoury aromatics during slow cooking that build the sauce's base flavour.
Minced carrot
Adds gentle sweetness and body as it softens slowly in the butter.
Bovril
Adds concentrated savoury, meaty depth to the finished sauce.

The step that matters

Browning the butter and flour, then adding the water gradually. Cooking the flour in butter until brown builds colour and flavour, and its starch thickens best when the water is added slowly while stirring. Adding it all at once or stopping stirring can leave lumps and a pale, raw-tasting sauce.

Flavor stand-ins for the apple

The recipe marks apple as optional. How well each one fits the dish's main ingredients (butter, flour, onion, carrot, clove, pepper):

  1. Limebetter flavor fit
  2. Avocadobetter flavor fit
  3. Lemonbetter flavor fit
  4. Applethe original

Fit is the average pairing score against butter, flour, onion, carrot, clove, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
