Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and flavour as the fat base for the roux.
- Flour
- Starch thickens the liquid as it heats, giving the sauce body.
- Milk
- Adds creaminess and body to the sauce.
- Stock
- Adds savoury flavour and extra liquid to the sauce.
- Hard-boiled egg
- Adds chopped egg white for texture and mild flavour.
The step that matters
Gradually add the milk and boil until thick. Flour must be fully dispersed in the fat before the liquid goes in, and the milk should be added gradually while stirring. This prevents lumps and lets the starch swell evenly as the sauce thickens.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
