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

What each ingredient does

Cold beef
Browns in the pan to add savory flavor and a seared surface.
Onion
Softens and adds sweetness and aroma as it cooks in the fat.
Turnip
Provides the bulk of the mixture and its mild, earthy flavor.
Butter
Adds fat for richness and helps the vegetables brown in the pan.

The step that matters

Heat until very hot. The mixture needs enough heat to brown and crisp the surface rather than steam. Packed, moist vegetables cook unevenly if the pan is not hot enough, so the cook should heat it fully before serving.

Fit is the average pairing score against beef, onion, butter, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
