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

What each ingredient does

Onions
Release sweetness and savoury aroma as they soften and brown slowly in the pot.
Carrots
Add sweetness and body to the broth as they soften during simmering.
Parsnips
Contribute sweet, earthy flavour and body to the broth during long simmering.
Potatoes
Release starch into the liquid, giving the broth a slightly fuller texture.
Butter
Adds fat that carries aroma and gives the broth a rounder mouthfeel.
Celery
Adds fresh, aromatic background flavour to the broth.

The step that matters

Bring the mixture to a boil until the water evaporates. With only half a cup of water, the vegetables and butter can scorch on the base of the pot before the liquid is gone. Stirring and keeping the heat moderate helps the vegetables soften and brown evenly without burning.
