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 ↓
Sour Cream Cookies. No. 1
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
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs well.
Add the sugar, melted butter, and sour cream or milk to the eggs.
Dissolve the baking soda in the milk and mix it into the batter.
Gradually add flour until the dough is manageable but not too stiff.
Flavor the dough with essence of lemon.
Shape and bake
Roll out the dough to a thickness of your choice, but do not roll very thin.
Cut into desired shapes and place on a baking sheet.
Bake in the preheated oven until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add structure and richness.
- Sugar
- Adds sweetness and helps the cookies brown lightly.
- Melted butter
- Adds fat for tenderness and flavor.
- Sour cream
- Adds moisture and acidity that tenderizes the dough.
- Baking soda
- Reacts with the acidic sour cream to help the cookies rise.
- Flour
- Provides the structure that holds the dough together.
The step that matters
Adding the flour. Flour should be added gradually until the dough is manageable but not stiff. Too much flour makes the cookies dense and dry, since flour proteins and starch absorb liquid and firm up the dough.
