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 ↓

Ingredients
Directions
The book says “a moderate 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 bowl, cream together the sugar and butter.
Add the chopped nuts, sour cream, eggs, baking soda, and salt. Mix well.
Gradually add flour until a stiff dough forms that can be rolled out thin.
Shape and bake
Roll out the dough and cut into rounds.
Place the rounds on a baking sheet and bake until golden.

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
- Adds sweetness and helps the dough brown as it bakes.
- Butter
- Adds fat and richness, giving the cookies tenderness when creamed with sugar.
- Chopped nuts
- Add flavour, texture and body to the dough.
- Eggs
- Bind the dough and add structure as they set in the oven.
- Baking soda
- Reacts with the acidic sour cream to lift the dough and aid browning.
- Sour cream
- Adds acidity and moisture, which activates the baking soda and keeps the cookies tender.
The step that matters
Gradually add flour until a stiff dough forms. Adding too much flour makes the dough dry and tough, while too little leaves it too soft to roll out thin and cut cleanly. Adding it gradually lets you stop once the dough is stiff enough to roll.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, butter, cream, egg, flour):
- Almondfits better
- Pistachiofits better
- Macadamia nutfits better
- Nutsthe original
Fit is the average pairing score against sugar, butter, cream, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
