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 ↓
Oatmeal Cookies
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the dough
In a bowl, beat the eggs without separating the whites and yolks.
Add the sugar, softened butter, and vanilla extract, and mix for 4-5 minutes.
In another bowl, combine the oatmeal, baking powder, and salt.
Stir the dry ingredients into the wet mixture until well combined.
Bake
Drop teaspoonfuls of the mixture onto buttered baking pans, shaping them into rounds.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add structure and richness as they set in the oven.
- Sugar
- Adds sweetness and helps the cookies brown as they bake.
- Softened butter
- Adds fat and tenderness, and carries flavor through the dough.
- Oatmeal
- Forms the body of the cookie and gives a chewy, hearty texture.
- Baking powder
- Releases gas during baking so the cookies rise and lighten.
The step that matters
Mixing the sugar, butter, and vanilla. Beating sugar with butter traps air in the fat, which helps the cookies rise and gives a lighter texture. Mixing for the full 4-5 minutes in the record matters for that aeration.
