Why it works: Cream and butter 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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 400°F (200°C).
Make and shape the dough
In a bowl, mix the egg, sour cream, sugar, baking soda, butter, and vanilla extract until well combined.
Roll the dough thin and cut into desired shapes.
Bake
Place on a baking sheet and bake for 8-10 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
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Sour cream
- Adds moisture and a slight tang that keeps the cookies tender.
- Sugar
- Sweetens the dough and helps the edges brown during baking.
- Baking soda
- Reacts with the acidic sour cream to lift the dough and aid browning.
- Butter
- Provides fat for richness and a tender, crisp texture.
The step that matters
Bake until just lightly golden. Cookies rolled thin cook quickly, and over-baking dries them out and makes them brittle. Pulling them when the edges are lightly golden keeps the centres soft and tender as they cool.
