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

What each ingredient does

Butter
Carries the flour and adds richness as the roux forms.
Flour
Thickens the sauce when cooked with fat, and browning it adds a deeper flavor.
Stock
Forms the liquid base that the roux thickens into a sauce.
Caramel
Deepens the color and adds a toasty, sweet flavor to the sauce.
Lemon juice
Adds acidity that brightens the rich, savory sauce.

The step that matters

Browning the flour in the butter. Cooking the roux slowly until nicely browned builds flavor and color, but too little heat leaves it pale and raw-tasting, while too much heat or stirring neglect scorches it and gives a bitter taste. Constant gentle stirring keeps it even.

Swap the lemon
