Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the dressing as it cooks gently into the hot liquid.
- Cheese
- Melts into the dressing, adding richness and savory flavor.
- Vinegar
- Adds acidity that sharpens the dressing and balances the cheese.
- Potatoes
- Form the body of the salad and soak up the dressing.
The step that matters
Gradually stir the egg mixture into the simmering water. Adding beaten egg too quickly can cause it to scramble instead of thickening smoothly. Slow addition while stirring gently spreads the heat so the egg sets into a smooth, even dressing.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (egg, vinegar, cheese, potato, mustard):
- Dillfits better
- Capersfits better
- Tarragonfits better
- Celerythe original
Fit is the average pairing score against egg, vinegar, cheese, potato, mustard. Candidates are from the same food group and used in at least 100 recipes.
