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

What each ingredient does

Butter
Carries the frying of the bacon and vegetables and, with the flour, forms the base roux.
Flour
Thickens the sauce when cooked in fat and stock, giving it body.
Brown stock
Forms the liquid base that gives the sauce its main flavour and body.
Ham or bacon
Adds smoky, savoury flavour that carries through the long simmer.
Tomato
Adds acidity and colour, balancing the richness of the stock and roux.
Sherry
Adds aromatic sweetness and acidity at the end, brightening the sauce.

The step that matters

Cooking the flour until golden brown. Cooking the flour in fat browns it and develops nutty flavour while it thickens. Undercooked flour tastes raw and pasty, while overcooked flour loses thickening power and turns bitter.

Swap the tomato

How well each one fits the dish's main ingredients (butter, flour, carrot, onion, shallot, ham, mushroom):

  1. Leekfits better
  2. Chivefits better
  3. Turnipfits better
  4. Tomatothe original

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