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 ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Beat the egg whites until stiff. Add the egg yolks and beat again.
In a bowl, mix the cream of tartar and baking soda with the flour. Combine the flour mixture with the granulated sugar.
Add the beaten eggs and mix until very stiff. Flavor with vanilla extract.
Bake
Bake at 400°F (200°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten until stiff, they trap air and give the cookies lift and a light structure.
- All-purpose flour
- Provides the main structure that sets as the cookies bake.
- Granulated sugar
- Adds sweetness and helps the cookies brown as they bake.
- Cream of tartar
- Stabilizes the beaten egg whites so they hold their foam longer.
- Baking soda
- Reacts with acidity in the mixture to produce gas that helps the cookies rise.
The step that matters
Beat the egg whites until stiff. Well-beaten egg whites hold air bubbles that lift the dough. Under-beaten whites collapse, and over-mixing after folding them in deflates the foam, leaving dense cookies.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, cream, flour, sugar):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, cream, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
