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 ↓
Crisp Cookies
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 400°F (200°C).
Make the dough
In a large bowl, beat the eggs and sugar together until well combined.
Add the baking powder, butter, and vanilla, mixing until smooth.
Gradually add flour until the dough is very stiff.
Shape and bake
Roll out the dough on a floured surface and cut into desired shapes.
Place the cookies on a baking sheet and bake in the preheated oven until crisp.

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
- Eggs
- Bind the dough and add structure as they set in the oven.
- Sugar
- Adds sweetness and helps the cookies brown and crisp as they bake.
- Baking powder
- Releases gas that lifts and lightens the dough as it bakes.
- Butter
- Adds fat and richness, contributing tenderness and flavor to the cookies.
- Flour
- Provides the structure that holds the dough together when rolled and cut.
The step that matters
Gradually add flour until the dough is very stiff. Adding flour gradually lets you judge the dough's texture. Too much flour makes cookies dry and tough, while too little leaves the dough too soft to roll and cut cleanly.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, butter, flour):
- Raisinfits better
- Vanillathe original
- Figfits less well
- Lemonfits less well
Fit is the average pairing score against egg, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
