Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Grapefruits
Provide the main fruit flavour, with tart and bitter notes that the dressing balances.
Olive oil
Adds fat and body to the dressing, carrying flavour and giving it a smooth mouthfeel.
White vinegar
Adds acidity that cuts the richness of the oil and brightens the grapefruit.
Powdered sugar
Adds sweetness that softens the sharp acidity and bitterness of the grapefruit.

The step that matters

Pour the cold dressing over the salad and sweeten with powdered sugar before serving.. Powdered sugar dissolves easily in the dressing, so it blends evenly. Cold dressing keeps the chilled grapefruit crisp and fresh, and the salad should be served soon after dressing so the lettuce does not wilt.

Swap the grapefruit

How well each one fits the dish's main ingredients (lettuce, sugar, vinegar, olive):
