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

What each ingredient does

Eggs
Whole eggs and yolks thicken the base and give it a rich, custardy body.
Egg whites
Beaten whites trap air, giving the dessert a light, airy texture.
Gelatine
Sets the mixture as it cools, giving it a firm yet tender body.
Powdered sugar
Sweetens the dessert and dissolves smoothly into the egg base.
Lemon
Its juice and rind add tartness and bright citrus aroma.

The step that matters

Adding the gelatine while beating. Gelatine must be added gradually while beating constantly so it disperses evenly; poured in at once or left to stand, it can form lumps or set in strands instead of blending smoothly.

Swap the lemon

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