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

What each ingredient does

Veal scrag end of neck
Provides meat flavour and gelatin that enriches the broth's body as it simmers.
Mutton scrag
Adds deeper meaty flavour to the broth during long simmering.
Onions
Contribute savoury sweetness and aroma to the broth.
Turnip
Adds mild sweetness and earthy flavour to the broth.
French potato flour
Starch that thickens the broth when heated, giving it body.
Milk or cream
Adds richness and softness, mellowing the broth's flavour and texture.

The step that matters

Skim thoroughly after boiling. Foam and impurities rise to the surface when the broth first boils. Removing them keeps the broth clear and clean-tasting, and the later fat removal depends on a clean simmer.

Swap the turnip

How well each one fits the dish's main ingredients (veal, mutton, onion, potato, flour, milk):
