Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish trimmings and bones
- Provide the main body and gelatin-rich flavor that gives the stock its character.
- Onions
- Add sweetness and aromatic depth as they soften in the butter.
- Butter
- Carries the aromatics and helps extract their flavor at the start.
- Lemon juice
- Adds acidity that brightens the stock and balances the fish flavor.
The step that matters
Heat gradually and shake often. Covering and heating slowly, with frequent shaking, keeps the fish and vegetables from scorching on the pan base, which would give the stock a burnt, bitter taste.
