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

What each ingredient does

Onion
Softens and sweetens as it browns in butter, adding flavour to the base.
Butter
Carries the onion's flavour and adds richness to the sauce.
Flour
Thickens the broth into a smooth, lightly bodied sauce.
White broth
Forms the liquid of the sauce that coats the beans.
Boiled beans
Serve as the main vegetable, warmed through in the sauce.

The step that matters

Stir in the flour and moisten with broth. Adding the liquid gradually while stirring keeps the flour dispersed, so the sauce thickens smoothly instead of forming lumps.
