Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Italian Salad
Ingredients
Directions
Prepare the fish and vegetables
Rinse the shrimps in cold water and let them drain in a colander.
Boil the eels in salted water for 15 minutes, then cool, remove bones, and cut into pieces the same size as the shrimps.
Wash the celery stalks, split them lengthwise into quarters, and cut into ½ inch pieces.
Slice the cucumber pickles and mix them with the fish and celery.
Remove the outer layer from the pickled onions, chop them, and add to the mixture.
Make the dressing
In a skillet, heat the vinegar, mustard, onions, salt, and pepper until hot but not boiling.
In a bowl, beat the egg yolks and olive oil together, then stir in the milk.
Combine the milk mixture with the hot vinegar mixture, stirring until it thickens but does not boil.
Pour the dressing into the salad and mix well.
Garnish and serve
Garnish the salad with head lettuce leaves and young celery leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the warm dressing into a smooth, creamy coating for the salad.
- Olive oil
- Adds fat that gives the dressing body and a rich mouthfeel.
- Cider vinegar
- Provides acidity that sharpens the dressing and balances the rich yolks.
- Shrimps
- Supply the main seafood flavour and firm, tender bite to the salad.
- Eels
- Add a rich, meaty texture and savoury flavour as the main fish.
- Celery
- Adds crisp texture and fresh, aromatic flavour to the salad.
The step that matters
Thickening the dressing without boiling. Egg yolks set as they heat. If the mixture boils, the yolks can scramble and curdle, leaving a grainy dressing instead of a smooth, thick one. Stirring over gentle heat keeps it silky.
Swap the onion
How well each one fits the dish's main ingredients (shrimp, celery, cucumber, cider, vinegar, mustard, pepper):
- Lettucefits better
- Horseradishfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against shrimp, celery, cucumber, cider, vinegar, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
