Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and adds richness to the base.
- Flour
- Thickens the butter and milk into a smooth sauce.
- Milk
- Forms the liquid base that thickens into the sauce.
- Hard boiled egg yolks
- Add body and richness, helping the sauce turn creamy.
- Cold fish
- Main ingredient, warmed through in the finished sauce.
The step that matters
Add the flour and milk gradually while stirring. Flour thickens a liquid only when it is evenly dispersed. Stirring as the milk goes in helps prevent lumps and keeps the sauce smooth.
