Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Brown Sugar Cookies
Ingredients
Directions
The book says “a quick 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, mix together the brown sugar, eggs, and butter until well combined.
Dissolve the baking soda in a small amount of water and add it to the mixture.
Gradually add flour until the dough is firm enough to roll out.
Shape and bake
Roll out the dough and cut into desired shapes.
Place on a baking sheet and 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
- Brown sugar
- Adds sweetness and moisture, and contributes to a soft, chewy texture.
- Eggs
- Bind the dough and add structure and richness.
- Butter
- Adds fat for tenderness and flavor.
- Baking soda
- Reacts with the sugar's acidity to help the cookies rise and brown.
- Flour
- Provides the structure that lets the dough be rolled and cut.
The step that matters
Dissolve the baking soda fully before adding it. Baking soda needs to be evenly dissolved and mixed through the dough so it reacts uniformly. Clumps can leave bitter spots and uneven rising.
