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

What each ingredient does

Leg of lamb
Provides the meat that becomes tender during long, gentle simmering.
Bechamel sauce
Forms a creamy white coating that adds richness and a mild, smooth texture.
Carrots
Add gentle sweetness and aroma to the cooking liquid.

The step that matters

Skim off the scum after the slow boil. Scum is coagulated protein and impurities that rise as the liquid heats. Removing it keeps the broth clearer and cleaner in flavor. Skimming before adding the herbs and vegetables keeps the stock from turning cloudy or bitter.

Swap the thyme
