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 ↓
Egg Kisses
Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Beat the egg whites until stiff peaks form.
Gently fold in the powdered sugar.
Add vanilla extract to taste.
Shape and bake
Drop tablespoonfuls of the mixture onto parchment paper, spacing them ½ inch apart.
Bake until the tops are light brown.
Finish
Remove from the oven, slide a knife under each kiss, and sandwich two together.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into stiff peaks, they trap air and give the cookies their light, airy structure.
- Powdered sugar
- Folded into the whipped whites, it sweetens the cookies and helps stabilize the meringue-like mixture.
The step that matters
Beating the egg whites until stiff peaks form. Egg whites must be whipped enough to hold air. Under-beaten whites produce flat, dense kisses, while over-folding after whipping deflates the foam and loses the airy texture.
