Make the sauce

Finish

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Flour
- Thickens the liquid into a smooth sauce as its starch swells with heat.
- Hard-boiled eggs
- Add body, texture and a mild, rich flavor to the sauce.
The step that matters
Simmer without boiling. Gentle heat lets the flour's starch swell and thicken the sauce evenly while cooking out its raw taste. Vigorous boiling can make the sauce lumpy, thin or scorch on the bottom of the pan.
“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.
