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 Jumbles
Ingredients
Directions
The book says “a slow 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 large bowl, cream together the butter and sugar.
Add the beaten eggs and sour cream, mixing well.
Stir in the baking soda and gradually add the flour until the dough is stiff enough to roll.
Shape and bake
Roll out the dough on a floured surface and cut into desired 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
- Creams with sugar to add richness and a tender texture.
- Sugar
- Sweetens the cookies and helps create a tender crumb when creamed with butter.
- Eggs
- Bind the dough and add structure and richness.
- Sour cream
- Adds moisture and tang, keeping the cookies soft.
- Baking soda
- Reacts with the sour cream's acidity to help the cookies rise and brown.
- Flour
- Provides the structure that makes the dough stiff enough to roll and cut.
The step that matters
Adding the flour gradually. Flour develops gluten as it is mixed, so adding too much or overworking the dough makes cookies tough. Add flour slowly and stop once the dough is stiff enough to roll.
