Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the syrup that sets into a sweet, spreadable frosting.
- Egg white
- Its proteins whip into a foam that gives the frosting body and lightness.
- Lemon juice
- Adds acidity that balances the sweetness and brightens the flavour.
The step that matters
Pouring the syrup into the egg white. The syrup must be hot and poured slowly while beating constantly. Pouring too fast or letting the mixture stop moving can cook or deflate the foam, leaving the frosting thin or grainy.
Swap the lemon
How well each one fits the dish's main ingredients (vanilla, sugar, egg):
