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

What each ingredient does

White fish trimmings
Provides the main flavour and body of the stock as they release gelatin and taste while simmering.
Onions
Add sweetness and savoury depth to the stock as they cook down.
Carrots
Contribute natural sweetness and a rounder background flavour to the stock.

The step that matters

Skimming the surface while simmering. Impurities and foam rise to the surface during simmering. Skimming them off keeps the stock clear and free of bitter or cloudy flavours.
