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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Adds richness and fat, giving the icing a smooth, creamy body.
- Confectioner's sugar
- Provides sweetness and bulk, forming the body of the icing.
- Boiling water
- Dissolves the sugar and loosens the mixture to a spreadable consistency.
The step that matters
Stir in the boiling water and vanilla extract until smooth. Adding too much liquid at once can thin the icing too far. Adding it gradually and stirring until smooth keeps the texture spreadable and free of lumps.
