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

What each ingredient does

Fish trimmings
Provide the main flavor and gelatin-rich body of the stock as they simmer.
Onions
Add sweetness and aromatic depth to the stock.
Celery
Adds subtle savory, aromatic flavor to the stock.
Dry white wine
Adds acidity and brightness that lift the flavor of the stock.

The step that matters

Skimming the scum and surface. Foam and impurities rise as the liquid heats; removing them keeps the stock clear and prevents off, bitter flavors from being reincorporated as it simmers.

Swap the celery
