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 white
- Provides structure and body, helping the icing whip up and hold its shape.
- Confectioners' sugar
- Adds sweetness and bulk, forming the smooth body of the icing.
- Vanilla extract
- Adds aroma and flavor to the icing.
The step that matters
Gradually beat in the confectioners' sugar. Adding the sugar slowly lets it dissolve and blend evenly into the egg white, preventing lumps and a grainy texture in the finished icing.
