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

What each ingredient does

Flour
Browned with the butter, it thickens the stock into a body-rich sauce.
Butter
Carries the fat that fries the ham and vegetables and carries their flavour into the sauce.
Turtle stock
Forms the liquid base of the sauce and supplies its main savoury flavour.
Ham or bacon
Frying releases savoury fat and flavour that season the whole sauce.
Tomato pulp
Adds acidity and body, balancing the richness of the stock and fat.
Sherry
Adds acidity and aromatic depth to the finished sauce.

The step that matters

Browning the flour. Flour cooked in fat gains flavour and colour, but it can scorch quickly. Scorched flour turns the sauce bitter and dark, so it must be stirred constantly over moderate heat.

Swap the tomato

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

  1. Leekfits better
  2. Shallotfits better
  3. Parsnipfits better
  4. Tomatothe original

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