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

What each ingredient does

Grapefruit
Provides the main fruit flavour, juicy tartness and the edible sections.
Powdered sugar
Dissolves quickly on the cut fruit, adding sweetness to balance the grapefruit's acidity.

The step that matters

Loosening the sections without cutting the skin. A sharp knife cuts along the membrane between the fruit and the skin. Cutting through the skin can release bitter oils and make the shell look ragged when served.

Swap the grapefruit

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