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

What each ingredient does

Onions
Browning in butter adds savory, deeper flavor to the broth.
Carrots
Release sweetness and body into the liquid as they simmer.
Butter
Carries the aromatics and adds richness to the broth.
Vinegar
Adds acidity that helps draw flavor out of the vegetables and herbs.

The step that matters

Browning the carrots and onions. Stirring until they just begin to brown builds deeper flavor through browning reactions. Pale vegetables make a flatter, less savory broth, while over-darkened ones can taste bitter.
