Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fish Salad
Ingredients
Directions
Prepare
Let the boiled halibut cool completely.
In a bowl, combine salad oil, vinegar, salt, and pepper to make a French dressing.
Assemble and chill
Pour the dressing over the cooled fish in the serving bowl.
Garnish with beets, carrots, onions, lemon slices, and any colorful cold vegetables.
Cover and refrigerate overnight before serving.
This salad can be kept for up to a week if stored very cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled halibut
- Forms the main body of the salad as a flaky, cold protein.
- Salad oil
- Adds moisture and richness, carrying flavor through the dressing and coating the fish.
- Vinegar
- Adds acidity that sharpens the flavor and helps firm the fish's surface.
The step that matters
Cooling the halibut completely before dressing. Pouring dressing over warm fish can make it break apart and turn mushy, and warm fish can absorb oil unevenly. Cooling it fully keeps the flakes intact and lets the dressing cling evenly.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, pepper, carrot, lemon):
- Capsicumfits better
- Broccolifits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against vinegar, pepper, carrot, lemon. Candidates are from the same food group and used in at least 100 recipes.
