Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

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 together the sugar and butter.
Add the sour cream and eggs, mixing well.
In another bowl, combine the flour, baking soda, salt, and nutmeg.
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Shape and bake
Roll the dough very thin on a floured surface.
Sprinkle a little sugar on top of the rolled dough.
Cut into desired shapes and place on a baking sheet.
Bake for 10-12 minutes or until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air and adds richness and tender texture.
- Sugar
- Sweetens the cookies and helps them brown lightly while baking.
- Sour cream
- Adds moisture and acidity that keep the cookies tender.
- Eggs
- Bind the dough and add structure and richness.
- Flour
- Provides the main structure of the cookie dough.
- Baking soda
- Reacts with the sour cream's acidity to lift and lighten the dough.
The step that matters
Roll the dough very thin. Thin dough bakes quickly and evenly, so the cookies turn crisp and lightly golden rather than thick and cakey. Thicker pieces stay soft in the middle and may need more time.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
