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

What each ingredient does

Corn starch
Thickens the boiling liquid into a smooth, sliceable custard-like layer.
Egg whites
Whipped with sugar to form a light, airy topping that holds its shape.
Sliced oranges
Provide the fruit base and fresh, bright flavour under the thickened layer.
Lemon juice
Adds acidity that brightens the sweet thickened liquid.

The step that matters

Stir and boil for 15 minutes. Corn starch only thickens fully once it boils, and it must be stirred to prevent lumps and scorching on the bottom of the pot. Boiling long enough gels the starch so the layer sets when cooled.

Swap the lemon

How well each one fits the dish's main ingredients (coffee, sugar, corn, orange, egg, vanilla, cream):
