Why it works: Olive and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 29,779 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
French Dressing
Ingredients
Directions
Make the dressing
In a shallow bowl, combine the slice of onion and small piece of ice.
Add the olive oil, salt, and paprika.
Stir with a fork until the oil thickens.
Gradually add the vinegar until the dressing is consistent.
Dress the salad
Pour over crisp lettuce leaves in a salad bowl.
Toss gently with a fork and spoon to combine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Forms the body of the dressing and carries the flavor of the other ingredients.
- Vinegar
- Adds acidity that brightens the oil and balances its richness.
The step that matters
Stir until the oil thickens. Stirring while adding the oil slowly breaks it into tiny droplets that stay suspended, so the dressing looks thick and cohesive instead of separating into layers.
Swap the onion

Fit is the average pairing score against olive, vinegar. Candidates are from the same food group and used in at least 100 recipes.
