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 as they set during cooking, giving it a rich, smooth body.
- Egg whites
- Folded in when beaten, they lighten the dressing and add airy texture.
- Neufchatel cheese
- Provides a soft, creamy base layer that holds the sandwich together and adds moisture.
- Vinegar
- Adds acidity that sharpens the flavor and balances the sweetness and richness.
- Butter
- Adds fat for a smoother, richer dressing texture.
The step that matters
Cook until thickened. Egg yolks thicken as their proteins set with gentle heat. If the heat is too high or cooking goes on too long, they can scramble and turn grainy, so the dressing should be cooked slowly over a double boiler and stirred until it just coats a spoon.
Swap the mustard
How well each one fits the dish's main ingredients (bread, cheese, sugar, butter, vinegar, egg, olive):
- Capsicumfits about as well
- Mustardthe original
- Tomatofits about as well
- Asparagusfits less well
Fit is the average pairing score against bread, cheese, sugar, butter, vinegar, egg, olive. Candidates are from the same food group and used in at least 100 recipes.
