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 ↓
Chocolate 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.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a large bowl, cream the butter and sugar together.
Add the eggs one at a time, mixing well after each addition.
Stir in the grated chocolate.
In a separate bowl, combine the flour and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Shape and bake
Roll the dough thin and cut into desired shapes.
Place on a baking sheet and bake for 10-12 minutes or until lightly golden.
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
- Butter
- Creams with sugar to trap air and add richness and tenderness to the cookies.
- Sugar
- Sweetens the dough and, creamed with butter, helps give a tender crumb and golden browning.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Eggs
- Bind the dough and add moisture and structure as they set in the oven.
- Grated chocolate
- Adds chocolate flavor and fat, and melts slightly to give richness.
- Baking soda
- Reacts with the dough's acidity to lift the cookies and promote browning.
The step that matters
Mixing in the dry ingredients. Overmixing once the flour is added develops gluten, which makes cookies tough. Mix only until just combined so the texture stays tender.
