Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
White Frosting
Ingredients
Directions
Make the syrup
Combine sugar and water in a saucepan and stir to prevent sticking.
Heat the mixture to a boil without stirring until it threads when dropped from a spoon.
Wash down sugar granules by dipping your hands in cold water and quickly into the hot syrup, repeating several times.
Finish the frosting
Gradually pour the syrup onto the beaten egg white while constantly beating the mixture.
Continue beating until the frosting reaches a spreadable consistency.
Add vanilla extract and spread on cake.

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, glossy frosting as it cools.
- Egg white
- Beaten into foam, it gives the frosting its light, airy structure.
The step that matters
Pouring the hot syrup onto the egg white. Pour the syrup slowly while beating constantly. Pouring too fast can deflate the foam, and the syrup must be hot enough to cook the egg white and set the frosting.
