Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the juicy, acidic base that forms the body of the cocktail.
- Peppers
- Add crisp texture and a fresh, slightly bitter vegetal flavour.
- Onion
- Adds sharp pungency; soaking in cold water mellows its harshness and sulphur bite.
- French dressing
- Supplies fat, acidity and seasoning that coat the vegetables and carry flavour.
The step that matters
Soaking the onion. Soaking finely chopped onion in cold water draws out some of its sharp sulphur compounds, giving a milder taste. Draining well keeps the cocktail from tasting watery or overly harsh.
