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

What each ingredient does

Fish bones
Release gelatin and flavour into the water, giving the stock body and taste.
Onion
Adds sweetness and savoury depth to the stock as it simmers.
Carrot
Adds subtle sweetness and aroma to the stock.

The step that matters

Skimming off the scum. Scum forms as the water first comes to a boil and contains coagulated proteins and impurities. Removing it keeps the stock clear and clean-tasting.

Swap the carrot
