Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites are sliced into the sauce and yolks, pushed through a ricer, make a fine powdered topping.
- Butter
- Melts with the flour to form a base that gives the sauce richness and body.
- All-purpose flour
- Mixed with the butter, its starch thickens the milk into a smooth, creamy sauce.
- Milk
- Forms the liquid of the sauce, which thickens as the starch cooks and sets it creamy.
The step that matters
Blending the flour and butter smooth before adding milk. Rubbing the butter and flour together until smooth lets the flour disperse evenly, so the milk thickens into a lump-free sauce rather than clumps.
