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

What each ingredient does

Olive oil
Provides fat that gives the dressing richness and a smooth, body-rich mouthfeel.
Lemon juice
Adds acidity that brightens the flavor and balances the richness of the oil.
Orange juice
Adds acidity and a touch of sweetness that softens the sharpness of the lemon.
Grated onion
Contributes pungent aroma and sharp flavor that gives the dressing its savory bite.

The step that matters

Shake until smooth and slightly thickened. Shaking breaks the oil into tiny droplets dispersed in the acidic juices, forming a temporary emulsion. Too little shaking lets the oil separate into layers. The mustard helps the mixture hold together longer.

Swap the onion

How well each one fits the dish's main ingredients (olive, lemon, orange, parsley, sauce, mustard):
