Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and carries flavour through the sauce.
- Flour
- Thickens the milk as its starch swells with heat, giving the sauce body.
- Milk
- Forms the liquid base that the flour thickens into a smooth sauce.
- Hard-boiled eggs
- Add soft chopped pieces of texture and substance to the sauce.
The step that matters
Stir carefully until boiling.. Flour mixed into hot milk can lump or scorch on the base of the pan. Constant stirring keeps the starch dispersed, and the sauce must reach boiling for the starch to swell fully and thicken.
