Ingredients
Directions
Make the dressing
Beat the egg yolks thoroughly in a bowl.
Add salt, pepper, sugar, mustard, and butter; mix well.
Stir in the vinegar.
Place the bowl in a kettle of hot water and stir constantly until the mixture thickens.
Let it cool before using.
Dress and serve
Pour the dressing over 1 quart of finely chopped cabbage while hot and mix thoroughly.
Serve cold. This dressing is also great for lettuce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing and emulsify it into a smooth, creamy base when gently heated.
- Butter
- Adds richness and smooth body to the dressing.
- Vinegar
- Adds acidity that gives the dressing its sharp, tangy flavour.
- White sugar
- Balances the sharpness of the vinegar with a touch of sweetness.
- Prepared mustard
- Adds sharp flavour and helps stabilise the emulsion.
The step that matters
Thickening over hot water. Egg yolks thicken as they heat, but if the mixture gets too hot it can curdle or scramble. Stirring constantly over gentle hot water keeps the heat even so the dressing becomes smooth and thick rather than lumpy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, sugar, butter, vinegar):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Shallotfits less well
Fit is the average pairing score against egg, pepper, sugar, butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
