Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 29,030 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓
The recipe
Ingredients
Contains: fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the dressing
Mix vinegar, oil, oregano, mustard, reserved bean liquid, salt and pepper together in a bowl until they combine and become fairly viscous.
Assemble and chill
Mix tuna, beans, red onion, celery and garlic into the dressing, thus breaking the tuna up.
Keep it in the refrigerator for an hour before serving, but serve at room temperature.

Mustard and vinegar share little aroma chemistry, yet 14,067 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tuna
- Provides the main protein and flakes into the dressing to give the salad its body.
- Cannellini beans
- Add creamy texture and bulk, and their reserved liquid helps emulsify the dressing.
- Olive oil
- Carries the fat and flavour of the dressing and coats the other ingredients.
- Red wine vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil and tuna.
- Whole grain mustard
- Acts as an emulsifier that helps the oil and vinegar hold together as a viscous dressing.
The step that matters
Mixing the tuna into the dressing. Folding gently keeps the tuna in flakes and beans whole; overworking breaks the beans into a paste and makes the salad mushy.

Fit is the average pairing score against onion, beans, garlic, celery, mustard, red wine, vinegar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
