Spaghetti Salad
Ingredients
Directions
Prepare the spaghetti
Boil the spaghetti in salted water until soft.
Transfer the cooked spaghetti to a bowl of ice water to cool, then dry it on a soft towel.

Season the mixture with salt, white pepper, and paprika.
Pour salad dressing over the mixture.
Let the salad stand for 30 minutes.
Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spaghetti
- Forms the bulk of the salad and gives it a tender, chewy body.
- Eggs
- Add richness and body to the salad as they are chopped through the mixture.
- Salad dressing
- Adds moisture and creamy flavour that coats the pasta and other ingredients.
- Sharp cheese
- Adds savoury, tangy flavour and a little fat to the salad.
- White potato
- Adds starchy bulk and a soft texture that blends with the pasta.
The step that matters
Cool and dry the spaghetti before mixing. Cooked pasta that stays warm or wet absorbs dressing unevenly and turns soggy or greasy. Chilling in ice water stops the cooking, and drying removes surface water so the dressing clings and the salad holds its texture.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, egg, celery, cheese, onion, tomato, lettuce):
- Thymefits better
- Tarragonfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against potato, egg, celery, cheese, onion, tomato, lettuce. Candidates are from the same food group and used in at least 100 recipes.
