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
- Creamed to a smooth base that gives the sauce its richness and body.
- Powdered sugar
- Dissolves readily into the fat, adding sweetness and a smooth, fine texture.
- Egg white
- Whipped into a foam that traps air, making the sauce light and airy.
- Wine or fruit juice
- Adds acidity and fruity flavor that balances the sweetness of the sugar.
The step that matters
Folding in the egg white. The egg white's whipped foam holds air bubbles that give the sauce its lightness. Folding gently keeps those bubbles intact, while vigorous stirring deflates the foam and leaves the sauce dense.
