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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
In a bowl, mix together the sour cream, sugar, egg, and butter until well combined.
Add the baking soda and nutmeg, mixing thoroughly.
Gradually add flour until the dough is soft but not sticky.
Shape and bake
Roll the dough out thin and cut into desired shapes.
Bake in a preheated oven at 350°F (175°C) until lightly 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
- Sour cream
- Adds moisture and tang, keeping the cookies tender.
- Sugar
- Sweetens the dough and helps the cookies brown during baking.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Butter
- Adds fat for richness and a tender, crisp texture.
- Baking soda
- Reacts with the sour cream's acidity to lift the cookies and aid browning.
- Flour
- Provides the structure that holds the dough and its shapes.
The step that matters
Gradually add flour until the dough is soft but not sticky. Too much flour makes the cookies dry and tough, while too little leaves dough that sticks and spreads, so adding it gradually lets you stop at the right texture.
