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
Preheat your oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the sour cream and eggs, mixing well.
Stir in the baking soda and nutmeg.
Gradually add flour until the dough is soft and can be rolled out.
Shape and bake
Roll out the dough to your desired thickness and cut into shapes.
Place on a baking sheet and 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
- Creamed with sugar to trap air, giving the cookies a tender, rich texture.
- Sugar
- Creamed with butter to add sweetness and help the cookies brown lightly.
- Sour cream
- Adds moisture and mild acidity, contributing to a soft, tender crumb.
- Eggs
- Bind the dough and add structure as the cookies set in the oven.
- Baking soda
- Reacts with the sour cream's acidity to produce gas that helps the cookies rise.
The step that matters
Gradually add flour. Adding flour gradually lets you stop once the dough is soft and rollable. Too much flour makes the cookies dry and tough, since gluten develops as the dough is worked.
