Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts with the flour to form a roux that gives the sauce its body and richness.
- Flour
- Thickens the melted butter and liquids into a smooth, cohesive sauce as its starch gelatinizes.
- Milk
- Forms the creamy liquid base of the sauce and adds a mild, rich flavor.
- Stock
- Adds savory depth to the sauce and contributes to its liquid volume.
The step that matters
Remove from heat as soon as it reaches boiling point.. Milk-based sauces can scorch or form a skin and lumps if overheated. Stopping at the first boil keeps the sauce smooth and prevents the starch from breaking down with prolonged heating.
