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 ↓
Sour Cream 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 the oven to 400°F (200°C).
Make the dough
Cream together the butter and sugar.
Add the beaten eggs and mix well.
Combine the baking soda with the sour cream and add to the mixture.
Gradually add flour until the dough is thin enough to roll out.
Bake
Sprinkle lightly with sugar, cut into shapes, and bake in the preheated oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add richness and a tender texture.
- Sugar
- Adds sweetness and helps the cookies brown lightly on the surface.
- Eggs
- Bind the dough and add structure and richness.
- Sour cream
- Adds moisture and acidity that makes the cookies tender.
- Baking soda
- Reacts with the sour cream's acidity to help the cookies rise and brown.
- Flour
- Provides the structure that lets the dough be rolled out thin and hold its shapes.
The step that matters
Combine the baking soda with the sour cream. Baking soda needs an acid to react and produce gas for lift. Sour cream supplies that acid, so the two should be combined before going into the dough, so the leavening is evenly distributed.
