Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Calf's head
Provides the meat and gelatinous body of the soup once simmered until tender.
Butter
Fat that carries flavour and, with flour, forms the base for thickening the soup.
Flour
Thickens the strained liquid into a smooth, body-rich soup when cooked with butter.
Onions
Adds savoury sweetness and aromatic depth to the stock as it stews.
Anchovies
Adds deep savoury flavour that rounds out the stock without tasting distinctly fishy.

The step that matters

Stirring the flour into the butter and adding the liquid. Stirring the flour until smooth and adding the liquid gradually while stirring prevents lumps, because flour starch clumps when it meets liquid unevenly.

Swap the onion

How well each one fits the dish's main ingredients (clove, mace, nutmeg, butter, flour, veal):

  1. Shallotfits better
  2. Leekfits better
  3. Carrotfits better
  4. Onionthe original

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