Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Provides fat and body, carrying the flavor and giving the sauce a smooth, rich mouthfeel.
- Vinegar
- Adds acidity that sharpens the flavor and balances the richness of the oil.
- Onion juice
- Adds a savory onion aroma and flavor to the sauce.
The step that matters
Mix all ingredients together using an egg beater.. Oil and vinegar do not mix on their own. Vigorous beating breaks the oil into tiny droplets suspended in the acidic liquid, forming a temporary emulsion. Without enough beating, the oil stays in separate layers.
Swap the onion
How well each one fits the dish's main ingredients (olive, vinegar, pepper):
- Capsicumfits better
- Tomatofits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against olive, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
