Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat for richness and a rounded, savory flavor.
- Flour
- Thickens the sauce as its starch swells when heated with the liquid.
- Hard-boiled eggs
- Add body, mild richness, and texture to the sauce.
The step that matters
Soften the butter without melting it. Softened butter blends with flour into a smooth paste that disperses evenly in the water. Melted butter separates from the flour, which can leave lumps and an uneven sauce.
“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.
