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 as it cooks down.
Butter
Enriches the soup with fat and smooth richness when combined with flour.
Flour
Thickens the soup by forming a roux with the butter when boiled.
Port wine
Adds sweetness, depth and aroma to the finished soup.
Onions
Contribute savory sweetness and aromatic body to the stock.

The step that matters

Rub butter with flour until smooth, then boil for 2 minutes. Cooking the butter and flour together gelatinizes the starch and cooks out its raw floury taste. Boiling it smooth before adding it to the hot soup prevents lumps and gives even thickening.

Swap the mace
