Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
Make the frosting
Beat the egg white until stiff peaks form.
Gradually stir in the powdered sugar and cornstarch until well combined.
Ensure the mixture is thoroughly beaten before applying it to the cake.
Frost the cake
Invert a milk pan, place the cake on it, and spread the frosting evenly over the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Whipped into a foam that gives the frosting its light, airy structure.
- Powdered sugar
- Sweetens the frosting and adds body as it stiffens the whipped egg white.
- Cornstarch
- Stabilizes the foam and helps it hold its shape without weeping.
The step that matters
Beat the egg white until stiff peaks form. Egg white foam traps air and sets the frosting's structure. If it is underbeaten, the frosting stays runny and can deflate or slide off the cake once spread.
