Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the sauce and gives it a soft, creamy body.
- Bread
- Provides the absorbent base that soaks up the sauce and holds its shape.
- Flour
- Thickens the hot milk into a smooth sauce as its starch swells with heat.
- Butter
- Adds richness and a smooth, silky mouthfeel to the finished sauce.
The step that matters
Dissolving the flour in cold milk before adding it to the hot milk. Flour added directly to hot liquid clumps, because its starch surface gels before it can disperse. Mixing it into cold milk first separates the particles so the sauce thickens smoothly.
