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 says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the egg whites until very stiff.
Gradually add the sugar while continuing to beat.
Mix in the vanilla, flour, lemon juice, and nut crumbs.
Bake
Drop small mounds of the mixture onto an ungreased baking pan.
Bake in a slow oven at 300°F (150°C) until delicately browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff foam that gives the cookies their light, airy structure.
- Sugar
- Sweetens the mixture and stabilizes the whipped whites while adding body to the dough.
- Nut crumbs
- Supply nutty flavor and bulk, making the mounds rich and tender.
- All-purpose flour
- Adds a little structure so the mounds hold their shape while baking.
- Lemon juice
- Adds acidity that helps stabilize the beaten egg white foam.
The step that matters
Beat the egg whites until very stiff. Stiff egg whites trap air that leavens the mixture and sets its structure in the oven. Under-beaten whites stay loose and spread, while over-beaten whites turn dry and grainy and lose their ability to hold air.
