Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat that carries flavour and helps form the sauce's smooth, rich body.
- Flour
- Starch thickens the liquid as it heats, giving the sauce its body.
- Milk
- Forms the main liquid of the sauce, setting its base texture and mild flavour.
- Cream
- Adds fat that makes the sauce richer and smoother on the palate.
The step that matters
Stirring while the milk goes in and comes to a boil. Flour clumps when liquid is added unevenly. Constant stirring disperses the starch so it hydrates evenly, and the sauce thickens smoothly as it heats instead of forming lumps.
