Ingredients
Directions
Beat four eggs lightly, add one tablespoon mixed mustard, one-half teaspoon salt, five tablespoons vinegar, and a little cayenne pepper; mix well.
Stand the mixture in a dish filled with boiling water; when warm, add a tablespoon of butter and cook until a little thicker than custard, stirring constantly.
If desired, continue boiling until thicker, then thin with milk or cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the dressing as they cook, giving it a custard-like body.
- Vinegar
- Adds acidity that sharpens the dressing and balances its richness.
- Butter
- Adds fat that makes the dressing smoother and more rounded in texture.
- Mixed mustard
- Adds sharp flavour that complements the acidity and richness.
The step that matters
Cook over boiling water while stirring constantly. Egg proteins set gradually with gentle heat. Stirring constantly and using indirect heat from the water bath helps prevent the eggs from scrambling, which would leave the dressing curdled and grainy.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, vinegar, milk, butter, egg, pepper):
- Capsicumfits better
- Potatofits about as well
- Mustardthe original
- Asparagusfits about as well
Fit is the average pairing score against sugar, vinegar, milk, butter, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
