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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the dough
Preheat your oven to 350°F (175°C).
In a bowl, cream together the brown sugar and butter.
Beat in the egg.
Dissolve the baking soda in hot water and add it to the mixture.
Gradually add flour until a soft dough forms.
Drop spoonfuls of dough onto a baking sheet.
Bake and ice
Bake for 10-12 minutes or until lightly browned.
For the icing, boil the brown sugar, water, and butter together.
Pour the hot mixture over the beaten egg white and stir until combined.
Drizzle the icing over the cooled cookies.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Brown sugar
- Adds sweetness and moisture, and gives the cookies their caramel flavour.
- Butter
- Adds fat for tenderness and richness, and carries flavour through the dough.
- Egg
- Binds the dough and adds structure as the cookies set.
- Baking soda
- Reacts with the sugars and browns the cookies while helping them rise.
- Flour
- Provides the structure that holds the soft dough together as it bakes.
The step that matters
Bake until lightly browned, not longer. Baking soda and brown sugar brown quickly, so over-baking dries the cookies and turns them hard. Pull them when the edges are just golden to keep them soft in the centre.
