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 gelatin that give the soup its body and rich mouthfeel.
Butter
Carries the frying flavor of the ham and vegetables and, with flour, forms the thickening roux.
Flour
Browned with butter, it thickens the soup into a smooth, velvety body.
Lean ham
Fried at the start, it adds savory, browned depth to the stock.
Sherry
Added at the end, it contributes acidity and a fragrant, nutty aroma.

The step that matters

Thicken the soup with browned flour and butter. Flour must be cooked in the fat until it loses its raw taste and is stirred until boiling so it thickens evenly without lumps. Adding it to hot liquid unevenly causes clumps that do not smooth out.
