Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the vinegar mixture as they set with gentle heat, giving the dressing body.
- Vinegar
- Provides acidity that sharpens the flavor and balances the rich yolks and ham.
- Ham
- Adds savory, meaty flavor and texture throughout the dressing.
- Mustard
- Adds sharp, pungent flavor that cuts through the richness of the yolks.
The step that matters
Stir over medium heat until the mixture thickens. Egg yolks thicken as their proteins set with heat, but too much heat or too long can scramble them into lumps. Stirring constantly and keeping the heat moderate keeps the dressing smooth.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, egg, pepper, ham):
- Capsicumfits about as well
- Mustardthe original
- Cabbagefits less well
- Cucumberfits less well
Fit is the average pairing score against vinegar, egg, pepper, ham. Candidates are from the same food group and used in at least 100 recipes.
