Why it works: Vanilla and sugar 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Whips and sets into a light, glossy structure that holds the frosting together.
- Powdered sugar
- Provides sweetness and thickens the liquid into a spreadable frosting.
The step that matters
Adding powdered sugar gradually. Adding sugar in small amounts lets you control thickness, since too much at once can make the frosting stiff and hard to spread.
