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

What each ingredient does

Bones
Release gelatin and savoury flavour into the cold water as they slowly simmer.
Meat
Contributes savoury flavour and richness to the broth during the long simmer.
Onion
Adds sweet, savoury aroma that gives the stock depth.
Carrots
Add gentle sweetness and aroma to the broth.

The step that matters

Keep the mixture from boiling for the first 30 minutes. Starting in cold water and heating gently lets proteins and fats release slowly, so the stock stays clear; boiling early makes it cloudy and greasy.

Swap the onion
