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 ↓
Cream Cookies
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugar until smooth.
Add the sour cream and eggs, mixing well.
Stir in the baking soda and enough flour to form a soft dough.
Shape and bake
Roll out the dough thinly on a floured surface.
Sprinkle the rolled dough generously with sugar and lightly roll over it with a rolling pin.
Cut into desired shapes and place on a baking sheet.
Bake in the preheated oven until lightly golden.

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 add richness and a tender, smooth texture to the dough.
- Sugar
- Adds sweetness and, sprinkled on top, helps the cookies brown and crisp at the surface.
- Sour cream
- Adds moisture and acidity, keeping the cookies soft and tender.
- Eggs
- Bind the dough and add structure and richness as they set in the oven.
- Baking soda
- Reacts with the sour cream's acidity to produce gas that helps the cookies rise and lighten.
The step that matters
Sprinkling and rolling the sugar on the dough. Sugar pressed into the rolled surface caramelises during baking, giving browning and a slight crunch. Too little leaves the cookies pale and plain, while pressing too hard can toughen the dough.
“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.
