Ingredients
Directions
Make the base
Melt the butter in a saucepan.
Add the flour and stir until smooth, being careful not to brown.
Add the milk and bring to a boil.
Thicken and finish
Place the saucepan in another pan of hot water.
In a bowl, beat the eggs, celery salt, cayenne pepper, sugar, and mustard together.
Add the vinegar or lemon juice to the egg mixture.
Stir this mixture into the saucepan until it boils and thickens like soft custard, about five minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Proteins set as they heat, thickening the mixture into a soft custard.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
- Milk
- Forms the liquid base that gives the dressing its creamy body.
- Vinegar or lemon juice
- Adds acidity that brightens the dressing and balances the richness.
- Sugar
- Adds sweetness that softens the sharpness of the acid and mustard.
- Mustard
- Adds a sharp, pungent flavour that gives the dressing its tang.
The step that matters
Stirring the egg mixture into the hot sauce. Egg proteins can curdle if they get too hot too fast. Adding the egg mixture gradually while stirring, and keeping the sauce over gentle heat in a hot-water bath, lets it thicken smoothly.
Swap the celery
