Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Provides the fat that forms the body of the dressing and carries flavour.
- Tarragon vinegar
- Adds acidity and sharp aroma, and dissolves the dry seasonings.
- Powdered sugar
- Adds a little sweetness that balances the acidity of the vinegar.
The step that matters
Dissolve the mixture in tarragon vinegar. Dry seasonings dissolve far more readily in the acidic liquid than in oil. Dissolving them in vinegar first spreads salt, sugar, and pepper evenly before the oil is added, so the dressing tastes uniform rather than gritty.
Swap the tarragon
How well each one fits the dish's main ingredients (sugar, pepper, vinegar, olive):
