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 ↓
Butter 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 the oven to 400°F (200°C).
Make the dough
In a bowl, cream the butter and sugar together.
Add the grated lemon rind, eggs, baking powder, and vanilla; mix well.
Gradually add flour until a soft dough forms.
Bake
Drop spoonfuls of dough onto a baking sheet.
Brush the tops with beaten egg.
Bake until golden brown.

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
- Butter
- Adds richness and tenderness, and carries flavour through the dough.
- Sugar
- Sweetens the cookies and helps browning during baking.
- Eggs
- Bind the dough and add structure and moisture to the cookies.
- Flour
- Forms the dough's structure once it is gathered into a soft dough.
- Baking powder
- Produces gas that lightens the dough and helps the cookies rise.
The step that matters
Gradually add flour until a soft dough forms. Adding flour gradually and stopping once the dough is soft keeps the gluten from developing too much, which would make the cookies tough rather than tender.
