Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. 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.
Make the dough
In a bowl, mix together the sugar, flour, sour cream, baking soda, salt, and egg until combined.
Handle the dough lightly and quickly, then roll it out.
Bake
Cut into desired shapes and bake in a preheated oven at 400°F (200°C) until golden.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cookie together as it bakes.
- Sour cream
- Adds moisture and fat for a tender crumb, and its acidity helps the baking soda react.
- Baking soda
- Reacts with the sour cream's acidity to release gas, helping the cookies rise and brown.
- Sugar
- Sweetens the cookies and helps them brown at the edges as they bake.
- Egg
- Binds the dough and adds richness and structure as it sets in the oven.
The step that matters
Handle the dough lightly and quickly. Overworking flour develops gluten, which makes cookies tough rather than tender. Keeping the dough handling brief preserves a soft, tender texture.
