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
- Butter
- Creaming it with sugar traps air and gives the sauce a rich, creamy body.
- Granulated sugar
- Sweetens the sauce and, beaten with butter, helps create a light, airy texture.
- Egg white
- Beaten air bubbles lighten the sauce and give it a soft, fluffy structure.
- Vanilla
- Adds aroma that rounds out the sweetness and buttery flavor.
The step that matters
Gently fold in the beaten egg white last. The egg white's whipped air bubbles are what lighten the sauce. Stirring vigorously or overmixing deflates them, leaving a dense, heavy result. Fold with a light, sweeping motion until just combined.
