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.

Swap the onion
