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 hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, mix the sugar, sour cream, and butter until well combined.
Add the baking soda and salt, then gradually incorporate enough flour to form a stiff dough.
Bake and serve
Shape the dough into cookies and place them on a baking sheet.
Bake in a preheated oven at 350°F (175°C) until golden.
Allow to cool before serving.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the dough and helps the cookies brown as they bake.
- Sour cream
- Adds moisture and acidity to the dough, giving a soft, tender crumb.
- Butter
- Adds fat for richness and a tender texture.
- Baking soda
- Reacts with the sour cream's acidity to help the cookies rise and brown.
- Flour
- Provides the structure that lets the dough hold its shape as cookies.
The step that matters
Adding the flour gradually until the dough is stiff. Flour absorbs liquid and sets the cookie structure. Adding too much makes the cookies dry and dense, while too little makes them spread and turn out soft and flat.
