What each ingredient does
- Butter
- Melts into the water to form a rich, flavourful sauce that carries the other ingredients.
- Flour
- Thickens the butter and water into a smooth, lightly bound sauce.
- Hard-boiled egg
- Adds body and a mild, savoury richness to the sauce.
The step that matters
Rubbing the butter with the flour. The flour must be fully worked into the butter so it disperses evenly when the water is added. Unblended flour can clump and leave lumps in the sauce.
