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
- Butter
- Adds richness and fat, giving the frosting a soft, creamy texture and flavor.
- Egg whites
- Whipped into a stiff foam that gives the frosting its light, airy structure.
- Confectioner's sugar
- Sweetens the frosting and helps thicken it to a spreadable consistency.
The step that matters
Beating to the consistency of whipped cream. Egg whites must be stiffly beaten before the creamed mixture is added, or the frosting will not hold air. Beating until it resembles whipped cream builds volume; adding sugar only if needed keeps the texture from becoming too stiff or too sweet.
