Name: Sauce Tartare
Ingredients: 1 cup mayonnaise dressing; 4 tablespoons chopped pickles; 1 teaspoon fruit sugar; 1 tablespoon capers; 4 tablespoons chopped olives; 4 tablespoons chopped parsley; ½ teaspoon onion juice (optional)

Why it works: Capers and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,550 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mayonnaise dressing: Forms the creamy base that carries all the other ingredients.
Chopped pickles: Adds tangy acidity and a crisp texture.
Capers: Contributes a sharp, briny bite.
Chopped olives: Adds salty, savoury flavour and texture.
Fruit sugar: Adds a little sweetness to balance the acidity.

Fit is the average pairing score against sugar, capers, olive, parsley. 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).
