What each ingredient does

Tomatoes
Supply juicy body and bright acidity that moistens and freshens the salad.
Onion
Adds sharp aroma and flavour, which partial cooking mellows.

The step that matters

Cook the onion only until three-quarters done. Partial cooking softens the onion's harsh raw bite and sulfur-driven sharpness while it still keeps some texture. Cooking it fully makes it soft and mushy, so it loses the crisp contrast the salad needs.
